I should create an HTML page with an SVG map showing England's major rivers and canals.\n\nMajor waterways of England include:\n- River Thames (London, flows through southern England)\n- River Severn (longest river in UK, flows from Wales through Shrewsbury, Worcester, Gloucester to Bristol Channel)\n- River Trent (Stoke-on-Trent, Nottingham, flows north to join Humber)\n- River Great Ouse (East Anglia, through Bedford, Cambridge area to The Wash)\n- River Wye (border with Wales)\n- River Mersey (Liverpool)\n- River Tyne (Newcastle)\n- River Tees (Middlesbrough)\n- River Wear (Durham/Sunderland)\n- River Humber (estuary, Hull)\n- River Aire (Leeds)\n- River Ouse (Yorkshire, through York)\n- River Avon (Bristol - through Bristol, Bath)\n- River Exe (Exeter)\n- River Dart (Dartmouth)\n- River Tamar (Plymouth, border Cornwall/Devon)\n- River Eden (Carlisle)\n- River Ribble (Preston)\n- River Dee (Chester)\n- River Nene (Northampton, to The Wash)\n- River Witham (Lincoln, Boston)\n- River Stour (various)\n- River Medway (Kent)\n- River Itchen/Test (Southampton)\n\nCanals:\n- Grand Union Canal (London to Birmingham)\n- Leeds & Liverpool Canal\n- Manchester Ship Canal\n- Kennet & Avon Canal\n\nI need to draw an outline of England and then draw the rivers. Let me think about the geography coordinates.\n\nLet me set up a coordinate system. I'll use a viewBox of something like 0 0 800 1000, where England stretches roughly:\n- North: Scottish border (~55.8°N at Berwick)\n- South: ~50°N (Isle of Wight, but mainland ~50.7)\n- West: Cornwall ~-5.7°W\n- East: ~1.7°E (Kent/Norfolk)\n\nEngland's shape - I need to draw a recognizable outline. Let me approximate:\n\nKey coastal points (lon, lat):\n- Berwick-upon-Tweed: (-2.0, 55.77)\n- Newcastle area coast: (-1.4, 55.0)\n- Sunderland: (-1.38, 54.9)\n- Teesside: (-1.15, 54.63)\n- Whitby: (-0.6, 54.48)\n- Humber mouth: (0.1, 53.6) — Spurn Point (0.15, 53.58)\n- The Wash (north): (-0.2, 53.2)...

The Welsh border on land:\n- Chepstow: (-2.67, 51.64)\n- Monmouth: (-2.71, 51.81)\n- Hay-on-Wye: (-3.13, 52.07)\n- Knighton: (-3.05, 52.35)\n- Welshpool: (-3.15, 52.66)\n- Oswestry area: (-3.05, 52.86)\n- Wrexham: (-2.99, 53.05)\n- Chester: (-2.89, 53.19)\n- Dee estuary: (-3.1, 53.3)\n- Wirral/Liverpool: (-3.05, 53.4)... Mersey mouth (-3.02, 53.45)\n- Southport: (-3.01, 53.65)\n- Blackpool: (-3.05, 53.81)\n- Morecambe Bay: (-2.88, 54.07)... Fleetwood (-3.02, 53.92)\n- Barrow: (-3.23, 54.11)\n- Millom: (-3.27, 54.21)\n- Whitehaven: (-3.59, 54.55)\n- Workington: (-3.55, 54.65)\n- Maryport: (-3.5, 54.71)\n- Silloth: (-3.38, 54.87)\n- Solway Firth: (-3.15, 54.9)... border at (-3.05, 55.0) Gretna (55.0)\n- Scottish border: Gretna (-3.06, 54.99), then east along border: (-2.9, 55.05), (-2.6, 55.2), (-2.5, 55.3), (-2.3, 55.5), (-2.2, 55.65), Berwick (-2.0, 55.77)\n\nFor the map, let me convert lon/lat to SVG coordinates. Use a simple projection:\nx = (lon - lonMin) * scaleX\ny = (latMax - lat) * scaleY\n\nLet's use lonMin = -6.0, latMax = 56.0. Scale: to fit 800x1000 roughly. England spans lon -5.72 to 1.75 (7.47 degrees), lat 49.96 to 55.77 (5.81 degrees). Aspect ratio: at latitude ~52.5, 1 degree lon ≈ 68 km, 1 degree lat ≈ 111 km. So real aspect: width = 7.47*68 = 508 km, height = 5.81*111 = 645 km. Ratio height/width ≈ 1.27.\n\nLet me use scale: x = (lon + 6.0) * 100, y = (56.0 - lat) * 127. That gives width up to 7.75*100 = 775, height up to 6.04*127 = 767. Hmm, let me compute: with lat range to 49.96, y max = (56-49.96)*127 = 767. So viewBox 0 0 800 800 roughly. Add margins. Let me instead center: viewBox=\"-20 -20 840 840\" or similar.\n\nActually, let me compute coordinates for each point using x = (lon + 6.0)*100, y = (56.0 - lat)*127.\n\nCoastline points (lon, lat) -> (x, y):\n- Berwick: (-2.0, 55.77) -> x=400, y=(56-55.77)*127=0.23*127=29.2 -> (400, 29)\n- Border along: I'll draw the Scottish border as a polyline from Berwick westward to Gretna.\n - Berwick (400, 29)\n - (-2.2, 55.65) -> x=380, y=44.5 -> (380, 45)\n - (-2.35, 55.55) -> x=365, y=57 -> (365, 57)\n - (-2.55, 55.3) -> x=345, y=89 -> (345, 89)\n - (-2.7, 55.15) -> x=330, y=108 -> (330, 108)\n - (-2.9, 55.05) -> x=310, y=121 -> (310, 121)\n - Gretna (-3.06, 54.99) -> x=294, y=128 -> (294, 128)\n- Then down the west coast:\n - Solway: (-3.3, 54.9) -> x=270, y=140 -> (270, 140)\n - Silloth (-3.38, 54.87) -> (262, 144)\n - Maryport (-3.5, 54.71) -> (250, 164)\n - Workington (-3.55, 54.65) -> (245, 172)\n - Whitehaven (-3.59, 54.55) -> (241, 184)\n - (-3.4, 54.3) -> (260, 216) — St Bees Head area\n - Millom (-3.27, 54.21) -> (273, 230)\n - Barrow (-3.23, 54.11) -> (277, 242)\n - Morecambe Bay south: (-2.9, 54.0) -> (310, 254)\n - Fleetwood (-3.02, 53.92) -> (298, 264)\n - Blackpool (-3.05, 53.81) -> (295, 278)\n - Southport (-3.01, 53.65) -> (299, 298)\n - Mersey mouth/Liverpool (-3.02, 53.45) -> (298, 324)\n - Dee estuary/Wirral west (-3.15, 53.33) -> (285, 339)\n - Chester area land border: (-2.89, 53.19) -> (311, 357) — border with Wales starts\n- Welsh border (land) southward:\n - Wrexham (-2.99, 53.05) -> (301, 375)\n - Oswestry (-3.05, 52.86) -> (295, 399)\n - Welshpool (-3.15, 52.66) -> (285, 424)\n - Knighton (-3.05, 52.35) -> (295, 464)\n - Hay (-3.13, 52.07) -> (287, 499)\n - Monmouth (-2.71, 51.81) -> (329, 533)\n - Chepstow (-2.67, 51.64) -> (333, 554)\n- Bristol Channel / south coast eastward:\n - Avonmouth (-2.72, 51.5) -> (328, 572)\n - Weston (-2.98, 51.35) -> (302, 591)\n - Burnham (-3.0, 51.24) -> (300, 605)\n - Minehead (-3.47, 51.21) -> (253, 609)\n - Ilfracombe (-4.12, 51.21) -> (188, 609)\n - Hartland Point (-4.53, 51.02) -> (147, 633)\n - Bude (-4.55, 50.83) -> (145, 657)\n - Newquay (-5.08, 50.42) -> (92, 709)\n - St Ives (-5.48, 50.21) -> (52, 736)\n - Land's End (-5.72, 50.07) -> (28, 753)\n - Penzance (-5.55, 50.12) -> (45, 747)\n - Lizard Point (-5.2, 49.96) -> (80, 768)\n - Falmouth (-5.07, 50.15) -> (93, 744)\n - Fowey (-4.64, 50.33) -> (136, 721)\n - Looe (-4.45, 50.35) -> (155, 718)\n - Plymouth (-4.14, 50.37) -> (186, 716)\n - Start Point (-3.64, 50.22) -> (236, 735)\n - Dartmouth (-3.58, 50.35) -> (242, 718)\n - Torquay (-3.52, 50.46) -> (248, 704)\n - Exmouth (-3.4, 50.62) -> (260, 684)\n - Lyme Regis (-2.94, 50.72) -> (306, 672)\n - Portland Bill (-2.46, 50.51) -> (354, 698)\n - Weymouth (-2.48, 50.61) -> (352, 686)\n - Lulworth area (-2.25, 50.62) -> (375, 684)\n - Swanage (-1.95, 50.61) -> (405, 685)\n - Bournemouth (-1.88, 50.72) -> (412, 672)\n - Christchurch (-1.78, 50.73) -> (422, 670)\n - Solent: Portsmouth (-1.1, 50.79) -> (490, 663)\n - Selsey Bill (-0.79, 50.72) -> (521, 672)\n - Beachy Head (0.24, 50.74) -> (624, 669)\n - Hastings (0.59, 50.86) -> (659, 654)\n - Dungeness (0.98, 50.91) -> (698, 648)\n - Folkestone (1.17, 51.08) -> (717, 626)\n - Dover (1.32, 51.13) -> (732, 620)\n - Deal (1.4, 51.22) -> (740, 609)\n - Ramsgate/North Foreland (1.44, 51.37) -> (744, 590)\n - Margate (1.38, 51.39) -> (738, 587)\n - Thames estuary: (1.2, 51.5) -> (720, 573)\n - Clacton (1.15, 51.79) -> (715, 536)\n - Felixstowe (1.31, 51.95) -> (731, 515)\n - Aldeburgh (1.6, 52.15) -> (760, 490)\n - Southwold (1.68, 52.33) -> (768, 467)\n - Lowestoft (1.75, 52.48) -> (775, 448)\n - Great Yarmouth (1.73, 52.6) -> (773, 433)\n - Cromer (1.3, 52.93) -> (730, 391)\n - Sheringham...

So the estuary goes east and slightly southeast. Draw as a wide river/estuary.\n\n5. **River Ouse (Yorkshire)**: formed at York... flows from York (-1.08, 53.96) southeast through Selby (-1.07, 53.78) to Trent Falls (-0.69, 53.7). Tributary: River Aire from Leeds (-1.55, 53.8) through Castleford joining near Goole. River Wharfe joins.

I'll include major rivers prominently and maybe a few key canals shown differently (dashed lines).\n\nDesign considerations: This should be a beautiful, polished map. Let me create:\n- Ocean background with subtle texture/gradient\n- England landmass with fill and border\n- Rivers in blue with varying widths\n- Labels for rivers (rotated along rivers where possible)\n- Labels for major cities (London, Bristol, etc.) maybe as dots\n- Title, legend, compass rose\n- Decorative cartographic style — maybe a vintage/parchment look or a clean modern look\n\nLet me go for an elegant modern cartographic style: cream/parchment land, soft blue water, thin river lines with nice curves, serif labels italic for water (classic cartography convention: water features in italic serif blue).\n\nI'll use quadratic/cubic bezier curves for smooth rivers and coastline. Writing the whole coastline as smooth path with C/S commands is complex; I can use a polyline path with L commands but with enough points it looks okay-ish, but smooth is better. Alternatively, use path with points and apply a smoothing via `` with `stroke-linejoin=\"round\"`. With enough points, straight segments are fine.\n\nActually, I could use JavaScript to smooth the paths (catmull-rom to bezier conversion). That's cleaner: define point arrays in JS, generate smooth paths. The instructions say I can use script tags. Let me write a small script that takes arrays of [x,y] and builds smooth path strings using Catmull-Rom spline conversion. That will give a professional look.\n\nPlan:\n- HTML page, centered SVG map.\n- viewBox roughly \"0 0 820 800\" with some margin.\n- Sea: rectangle with gradient (light blue).\n- Land: England path (fill parchment #f5f0e1 or soft green-beige), stroke darker.\n- Scottish border & Welsh border: dashed lines to show boundaries.\n- Rivers: paths stroke #4a90c2 / #3d85c6 with round caps, widths 2-4.\n- Estuaries: wider filled shapes? Maybe just thicker strokes near mouths. Simpler: use two strokes — a wider translucent stroke under a thinner one.\n- City markers: small circles + labels (London, Birmingham? Birmingham isn't on a major waterway... but helpful for orientation. Include: London, Liverpool, Manchester, Leeds, Newcastle, Bristol, Southampton, Plymouth, Hull, York, Norwich?, Exeter, Carlisle, Oxford, Cambridge?, Nottingham, Gloucester, Worcester, Shrewsbury, Bedford...). Keep to ~15 to avoid clutter.\n- River labels: italic serif, blue, positioned with rotation.\n- Legend explaining river/canal/border lines.\n- Compass rose in a corner.\n- Title: \"Major Waterways of England\".\n\nLet me now carefully define the coastline points (already computed above). I'll refine to keep point count reasonable (~70 points).\n\nCoastline (clockwise from Berwick, including land borders):\nLet me list in order starting at Berwick, going WEST along Scottish border, then south along west coast, then east along south coast, then north along east coast back to Berwick.\n\n1.

From Margate: (1.3, 51.4) -> (730, 585); then (1.1, 51.5) -> (710, 572)? Hmm, the coast from Margate goes west into Thames estuary: Whitstable (-? 1.02, 51.36) -> (702, 602)? Wait Whitstable is at (1.02, 51.36) north Kent coast -> (702, 602). Hmm, that conflicts with my earlier point. Let me redo east coast more carefully.\n\nKent north coast: Margate (1.38, 51.39) -> Reculver (1.2, 51.38) -> Whitstable (1.02, 51.36) -> Sheerness (0.76, 51.44) -> Thames estuary north shore goes NORTH into Essex: actually the estuary: south shore is Kent (Sheerness, Grain), north shore is Essex (Southend (0.71, 51.54)). The outer estuary mouth is roughly between Margate/North Foreland and Harwich/Clacton.\n\nFor a stylized map, the coast path: ... North Foreland (744, 590) -> Margate (738, 587) -> (720, 583) -> Whitstable (702, 602)?? That creates a deep indent (Thames estuary on south side). Then Sheerness (676, 587)... then back out to Southend (671, 573)? Hmm this is getting complex. The Thames estuary: I want to show it as a notable estuary. \n\nSimplification: draw coast from North Foreland west along Kent to Sheerness-ish (680, 590), then the Thames estuary: go up (north) crossing to Essex at Southend (671, 573), then NE along Essex coast: (1.0, 51.75)? -> (700, 549)? Clacton (1.15, 51.79) -> (715, 536). Then Harwich/Felixstowe (731, 515), etc.\n\nActually let me make the Thames estuary a water feature: draw a wide blue estuary shape from London to the sea, and the coastline can go around it: coast path: North Foreland (744,590) -> (730, 586) -> Whitstable (702, 601) -> (690, 596) -> Sheerness (676, 588) -> then across the estuary mouth (water gap) -> Southend (671, 573) -> (690, 558) -> Clacton (715, 536) -> Felixstowe (731, 515) -> Aldeburgh (760, 490) -> Southwold (768, 467) -> Lowestoft (775, 448) -> Great Yarmouth (773, 433) -> (760, 415) -> Cromer (730, 391) -> (700, 385)? Sheringham/Wells: (1.0, 52.95)? -> (700, 388)? hmm Wells (0.85, 52.95) -> (685, 388). Hunstanton (0.49, 52.95) -> (649, 388). Then Wash: King's Lynn (639, 413) in, then back out: (630, 400)? Actually the Wash is a big square bay: from Hunstanton south to King's Lynn, then the coast goes west/northwest inside... The Wash: south shore King's Lynn (0.39, 52.75) -> (639, 413); west shore up to Boston/Skegness: (0.2, 52.9)? Boston is inland. Wash west shore: (-0.05, 52.95)? Hmm. The Wash outline: from Hunstanton (649, 388) go south to (639, 413) King's Lynn, then the coast turns NW: (615, 410) -> (605, 395)? -> Boston area (598, 390) -> then north to Skegness (634, 363). Actually the Wash's NW corner around Gibraltar Point (0.32, 53.1) -> (632, 367)? and Skegness (0.34, 53.15) -> (634, 363).\n\nSo coast: (649, 388) Hunstanton -> (640, 405) -> (639, 413) King's Lynn -> (625, 412) -> (612, 400) -> (605, 392) -> (615, 380) -> (632, 367) Gibraltar Pt -> (634, 363) Skegness -> (627, 337) Mablethorpe -> (620, 320) -> Cleethorpes (595, 310) — wait Cleethorpes (53.56, -0.03) -> (597, 311). Then Humber estuary: from Cleethorpes/Grimsby the coast follows the Humber west: but for the outline I'll draw coast crossing the Humber mouth: Cleethorpes (597, 311) -> Spurn Point (615, 308)? No wait, Spurn is on the north side of the Humber mouth. Grimsby/Cleethorpes on the south side. The Humber mouth is between Spurn (north) and Cleethorpes (south). So coast path: Skegness (634, 363) -> Mablethorpe (627, 337) -> (612, 322) -> Cleethorpes (597, 311) -> then jump across Humber mouth to Spurn (615, 308) -> Withernsea (603, 290) -> Bridlington (581, 244) -> Flamborough (592, 237) -> Filey (560, 226)? -> Scarborough (560, 219)? Filey (-0.29, 54.21) -> (571, 230). Scarborough (-0.4, 54.28) -> (560, 219). -> (548, 205) -> Whitby (540, 193) -> (515, 185) -> (500, 178) -> Tees mouth (485, 174) -> Hartlepool (480, 167) -> (472, 155) -> Sunderland (462, 138) -> (461, 132) -> Tyne mouth (460, 127) -> (455, 118) -> Blyth (450, 112) -> (445, 98) -> Amble (442, 85) -> (440, 72) -> (435, 53) Seahouses -> (428, 51) Bamburgh -> (420, 41) -> Berwick (400, 29). Close.\n\nThe estuaries (Thames, Humber, Wash, Severn, Mersey, Dee, Morecambe, Solway, Southampton Water, Plymouth, Portsmouth) — I'll render some as water-colored shapes overlapping the land to give estuary effect, or simply draw the coastline with gaps bridged and draw wide river strokes. Simpler approach: keep coastline as continuous (crossing estuary mouths at outer points) and draw rivers as blue strokes; for major estuaries (Thames, Humber, Severn, Wash), add translucent blue wedge shapes.\n\nHmm, but if the coastline \"crosses\" the Thames estuary from Sheerness to Southend, the land fill will cover the estuary... The coastline is a single closed path forming the land polygon. If I route the coast through the estuary mouth points, the estuary area becomes \"land\". I could instead route the coastline up the Thames: Sheerness -> along Kent side up to ~Gravesend, then back down the Essex side. That makes the map look right. Similarly for the Humber: route up the Humber to Hull/Goole and back. And the Wash as above. The Dee, Mersey, Solway similarly to a degree.\n\nLet me re-route the west coast for estuaries:\n- Solway: from Gretna (294,128), the border... Actually Gretna is at the head of the Solway; the border meets the sea there. Fine: (310,121) -> (294,128) -> then coast south: (280,135) -> (272,139)? -> Silloth (262,144). The Solway's south shore. Good enough.\n- Morecambe Bay: route inward: Barrow (277,242) -> (283,250) -> (295,255) -> (310,254) Morecambe -> (305,262) -> Fleetwood (298,266) hmm. Let me simplify: (277,242) -> (290,248) -> (305,252) -> (302,260) -> (298,266) -> Blackpool (295,278). OK.\n- Ribble estuary: minor, skip.\n- Mersey: Southport (299,298) -> Formby (300,308)? -> Crosby (298,316) -> Liverpool (298,324)... The Mersey estuary inner narrows. For style, I'll just draw the coast as a slight indent and draw the Mersey river wide. Simplify: coast continues (299,298) -> (298,324) -> (292,331) -> (280,338) Dee -> (285,345) -> (295,352) -> Chester (311,357).\n Dee estuary: from (280,338) [Hoylake] inland SE to Chester? The Dee estuary is between Wirral and Wales (Flintshire). Chester is at the head. Since Welsh border starts at Chester-ish, I can route: (280,338) -> (290,345) -> (300,350) -> (311,357) Chester. Good — gives an estuary indent.\n- Severn: from Chepstow (333,554) the coast crosses the Severn mouth. Route inward? The Severn estuary is wide; the \"coast\" between Chepstow and Avonmouth — the land border between England and Wales follows the Wye to Chepstow, then the Severn. For simplicity, go from Chepstow (333,554) straight to Avonmouth (328,572)? That line crosses water (Severn estuary) — it's roughly the England/Wales maritime boundary, acceptable on a stylized map. Or route via the Severn up to Gloucester and back — too fiddly. I'll draw straight-ish: (333,554) -> (330,563) -> (328,572).\n- Thames: route: North Foreland (744,590) -> Margate (738,587) -> (725,584) -> (712,590)? Hmm — the Kent north coast: Margate (1.38,51.39) -> (738,587); Reculver (1.2,51.38) -> (720,588); Whitstable (1.02,51.36) -> (702,603); Sheerness (0.76,51.44) -> (676,588)? Wait Sheerness lat 51.44 -> y=(56-51.44)*127=579. Let me recompute: (56-51.44)=4.56, *127=579. So Sheerness (676, 579)? Earlier I wrote 587 — recompute: lat 51.44 => y = 4.56*127 = 579.1. OK (676, 579). Whitstable lat 51.36 => y=4.64*127=589.3 => (702, 589). Reculver (1.2, 51.38): y=(4.62)*127=586.7 => (720, 587).\n Then up the Thames south bank: Sheerness (676, 579) -> (660, 575) -> Gravesend (0.37, 51.44) -> (637, 579)? lat 51.44 -> 579. Hmm Gravesend (0.37, 51.44): x=637, y=579. Then cross to Essex: Tilbury... north bank: (0.45, 51.47) -> (645, 575)? then Southend (0.71, 51.54) -> (671, 567)? lat 51.54 -> y=4.46*127=566. Then coast NE: (1.0, 51.7)? -> (700, 548)? Clacton (1.15, 51.79) -> (715, 536). \n Wait, but the Thames river itself will be drawn as a blue stroke from London to the estuary; the coast going up to Gravesend and back creates the estuary look. Gravesend is roughly opposite Tilbury; London is at (587, 572). The river stroke from London (587,572) to (637,579)/(645,575) then widening to sea. I'll draw the estuary as a filled blue shape polygon on top of land? No — the estuary region: if coastline goes Sheerness -> Gravesend -> Tilbury -> Southend, the area between is sea-colored? No! The land polygon boundary: ...coming from the north (Essex coast) down to Southend -> up to Tilbury -> across to Gravesend -> down to Sheerness -> then continues south/east along Kent... The region between Southend-Tilbury-Gravesend-Sheerness is OUTSIDE the polygon (sea). And west of Tilbury/Gravesend towards London: the polygon includes it as land, and I draw the Thames river stroke over it. The estuary between Gravesend and the sea will show as sea. \n\nOrder of coastline traversal matters. Going clockwise starting at Berwick down the WEST coast, around the south, up the EAST coast: when I reach the Thames from the south (Kent side: ...Dover, North Foreland, Margate, Whitstable, Sheerness), I then go up the Thames south bank to Gravesend, cross to north bank Tilbury, come back down to Southend, then continue up Essex coast (Clacton, Felixstowe...). Yes, that ordering works with my clockwise path.\n\nSimilarly Humber: coming from the south: Skegness -> Mablethorpe -> Cleethorpes (south bank of Humber mouth) -> up the Humber: Grimsby -> Immingham -> ... -> to Goole-ish/Trent Falls area -> back down north bank: Hull -> Spurn -> Withernsea -> Bridlington. Points: Cleethorpes (597, 311) -> Grimsby (593, 313) -> (585, 308) Immingham -> (575, 300) -> (565, 296) -> (555, 294) -> (545, 293) -> (531, 294) Trent Falls -> then north bank: (540, 290) -> (555, 288) -> Hull (567, 288) -> (585, 290) -> (600, 295) -> Spurn (615, 306) -> back out: (610, 300)? Hmm Spurn is a spit curving south. Simplify: after Hull: (590, 292) -> (605, 300) -> Spurn (615, 307) -> then Withernsea (603, 290)? Wait Withernsea is NORTH of Spurn on the outer coast. After rounding Spurn, go north: (608, 297) -> (603, 290) Withernsea -> (595, 270) -> (590, 255) -> Bridlington (581, 244) -> Flamborough (592, 237) -> Filey (571, 230) -> Scarborough (560, 219)...\n\nWash: coming from north? No — clockwise from Thames we go up the east coast: Felixstowe -> Aldeburgh -> Southwold -> Lowestoft -> Gt Yarmouth -> Cromer -> Wells -> Hunstanton -> into the Wash: south shore down to King's Lynn (639, 413) -> then west/north along inner Wash: (625, 412) -> (610, 405) -> (600, 395) -> (605, 385)? -> then up to Skegness (634, 363). The Wash inner NW corner: Boston is at the corner. Points: King's Lynn (639,413) -> (628,414) -> (615,408) -> (605,398) -> (602,390) -> (610,380) -> (620,372) -> (632,366) Gibraltar Point -> Skegness (634,363). Good.\n\nSolway: Scottish border ends at Gretna (294,128) at head of Solway. Coast goes south: (288,132) -> (278,138) -> (268,141) -> Silloth (262,144)... fine, mild indent.\n\nSouthampton Water / Solent / Portsmouth: coming clockwise from the west (Dorset): Swanage (405,685) -> Poole (398,682)? -> Bournemouth (412,672) — wait, order: going east: Swanage is east of Poole. Sequence west to east: ...Lulworth (375,684) -> (390,690) -> Swanage (405,685) -> then north into Poole Bay: Bournemouth (412,672) -> Christchurch (422,670) -> then Solent: (445,666) -> (462,657) Calshot? -> Southampton Water: up to (464,652) then back down (470,660) -> Portsmouth (490,663) -> (505,665) -> Selsey (521,672). Hmm the Solent north shore indents. Let me simplify with modest detail: (422,670) -> (440,665) -> (455,660) -> (464,652) [head of Southampton Water] -> (472,661) -> (490,663) Portsmouth -> (505,664) -> Selsey (521,672). Also the Isle of Wight — I could draw it as a separate small island south of the Solent: IoW shape around (-1.3,50.67): points: (455,690)? Cowes (-1.3,50.76) -> (470,667)?? no. Isle of Wight: lon -1.6 to -1.07, lat 50.6-50.77. Points: Needles (-1.57,50.66) -> (443,680); Freshwater; Newport (-1.29,50.7) -> (471,674); Ryde (-1.16,50.73) -> (484,670); Bembridge (-1.08,50.68) -> (492,678); Ventnor (-1.2,50.6) -> (480,687); St Catherine's (-1.3,50.58) -> (470,689); Chale; back to Needles. Draw small island: M (443,680) C ... to (492,678) ... close. I'll add it simply.\n\nPlymouth Sound: minor indent at (186,716): (183,713) -> (186,716) -> (192,717)? fine as is.\n\nPortland: spur — simplified above.\n\nNow rivers. I'll define each river as point arrays (already computed above; recompute y-values carefully with formula y=(56-lat)*127, x=(lon+6)*100).\n\nLet me recompute key city/river points precisely:\n\nConversion: x = (lon+6)*100; y = (56-lat)*127.\n\n- London (-0.127, 51.507): x=587.3, y=(4.493)*127=570.6 -> (587, 571)\n- Oxford (-1.257, 51.752): x=474.3, y=4.248*127=539.5 -> (474, 540)\n- Reading (-0.978, 51.454): x=502.2, y=4.546*127=577.3 -> (502, 577)\n- Windsor (-0.604, 51.482): x=539.6, y=4.518*127=573.8 -> (540, 574)\n- Kingston (-0.3, 51.41): x=570, y=4.59*127=582.9 -> (570, 583)\n- Dartford (0.22, 51.45): x=622, y=4.55*127=577.9 -> (622, 578)\n\nThames path: source (392,551) [(-2.08,51.67): x=392, y=4.33*127=549.9 -> (392,550)] -> (410,552)? -> Lechlade (-1.69,51.7): x=431, y=4.3*127=546 -> (431,547) -> Oxford (474,540) -> (490,555)? Abingdon (-1.28,51.67): x=472, y=550 — hmm Abingdon is south of Oxford: (472,550). Then Reading (502,577) -> Henley (-0.9,51.54): x=510, y=566? Henley is NE of Reading actually (-0.9,51.535): (510,567). Sequence: Oxford (474,540) -> Abingdon (472,550) -> Wallingford (-1.12,51.6): (488,558) -> Reading (502,577) -> Henley... wait Henley is downstream (east) of Reading: (510,567)? That'd be north — no: lat 51.535 > 51.454 so y=567 < 577. But geographically Henley is NE of Reading. OK (510,567) then Marlow (-0.78,51.57): (522,565) -> Windsor (540,574) -> Staines (-0.51,51.43): (549,580) -> Kingston (570,583) -> London (587,571)? Hmm London y=571 but Kingston y=583 — the Thames does flow north-east from Kingston to London. OK -> (600,573) -> Dartford (622,578) -> estuary (645,577).\n\nSimplify Thames points: (392,550) (431,547) (474,540) (488,558) (502,577) (522,565) (540,574) (555,581) (570,583) (587,571) (605,574) (622,578) (650,577).\n\nSevern: source in Wales at (-3.79,52.47): x=221, y=3.53*127=448.3 -> (221,448) — I'll start at border-ish (290, 430)? Let me start the drawn river just inside Wales near (300,432) [(-3.0,52.6): x=300, y=3.4*127=431.8]. Points: (300,432) -> Shrewsbury (-2.75,52.71): x=325, y=3.29*127=417.8 -> (325,418). Actually Severn loops around Shrewsbury; fine. -> Ironbridge (-2.48,52.63): (352,428) -> Bewdley (-2.32,52.38): (368,460) -> Worcester (-2.22,52.19): x=378, y=3.81*127=483.9 -> (378,484) -> Tewkesbury (-2.16,51.99): (384,509) -> Gloucester (-2.24,51.86): x=376, y=4.14*127=525.8 -> (376,526) -> (365,538) -> (-2.55,51.65): (345,553)? Framilode (-2.36? no). Let me route the Severn from Gloucester SW: (-2.4,51.75): (360,542) -> (-2.5,51.7): (350,548) -> (-2.6,51.62): (340,559) -> Berkeley (-2.46,51.69)? The river bends... simplify: (376,526) -> (362,540) -> (348,552) -> (340,563) -> mouth (330,571)? The Severn meets the sea around (-2.95,51.6)? The estuary: from Gloucester the Severn flows SW to the Bristol Channel, mouth near Avonmouth/Portishead (-2.9,51.5)? I'll end at (320,568) merging with coast near Avonmouth (328,572). Points: (300,432) (325,418) (352,428) (368,460) (378,484) (384,509) (376,526) (362,540) (348,552) (336,564) (322,569).\n\nWye (tributary-ish, joins Severn at Chepstow): (310,502) [(-2.9,52.05): x=310, y=3.95*127=501.7] -> Hereford (329,500) -> (340,510) -> Ross (342,519) -> (336,526) -> Monmouth (329,532) -> (331,543) -> Chepstow (333,554).\n\nAvon (Bristol): source (-2.28,51.53): x=372, y=4.47*127=567.7 -> (372,568) -> Chippenham (388,577) -> (-2.25,51.42) Melksham: (375,589) -> Bradford (-2.25,51.35): (375,598)? hmm Bradford-on-Avon (-2.25,51.35): x=375, y=4.65*127=590.6 -> (375,591)?? wait y=(56-51.35)*127=4.65*127=590.6.

Keep 18.\n\nRiver labels (italic serif, fill #2b6cb0 or darker #1f5f8b):\n- Thames: along the river near (520,590)? rotated slightly. Place \"River Thames\" at (520, 595) rotate(-6) or so. Actually Thames runs E-W around y 540-580; label at (470, 560)? Hmm Oxford is at (474,540) labeled above. Put \"Thames\" label below river around (510, 590)? Reading area. I'll place \"River Thames\" at (455, 575) rotate(-8)? Let me think: between Oxford (474,540) and Reading (502,577), the river descends. Label at (455,570) rotate(15)? I'll fine-tune with approximate angles.\n- Severn: label vertical-ish along the river near (395, 470) rotate(-75)? The Severn flows SSE from Shrewsbury to Worcester: at (385,450) rotate(-78).\n- Trent: label near (450,420)? The Trent flows NE then N. Label at (455,415) rotate(-30)? Or along Newark-Gainsborough vertical: (530,350) rotate(-85). Use (535,355) rotate(-82) \"River Trent\".\n- Great Ouse: (545,515)? The upper Ouse around Milton Keynes-Bedford: (520,515) rotate(-15). \n- Nene: (540,470) rotate(-25)? \n- Witham: (570,395) rotate(-35)? Hmm Lincoln-Boston: (575,390) rotate(35)? The Witham flows SE: angle +35 in screen coords. Place at (575,392) rotate(38)? Let me approximate.\n- Yorkshire Ouse: \"River Ouse\" near York: (505,270) rotate(75)? The Ouse flows SSE: label at (500,272) rotate(72).\n- Aire: (420,290)? near Leeds: (415,288) rotate(-20)? Aire flows ESE: (420,285) rotate(-15)? hmm Leeds at (445,279) with label. Put Aire label at (408,290) rotate(-18).\n- Tyne: (420,140) rotate(2) \"River Tyne\".\n- Wear: (420,180) rotate(18)? \"River Wear\" at (415,180).\n- Tees: (405,195) rotate(12)? \"River Tees\" at (400,198)? Hmm Tees at y~185. Label at (410,200).\n- Eden: (340,190) rotate(-25)? Eden flows NW: label at (345,185) rotate(-28).\n- Mersey: (355,345)? Mersey flows W: label at (360,348) rotate(5) \"River Mersey\".\n- Ribble: (350,300) rotate(-15)? hmm Ribble at (355,275)... label at (365,300) rotate(-20) \"River Ribble\"? Preston (330,286). Label at (350,302)? might collide with Mersey label. Ribble label at (360,268)? near Clitheroe (361,272): put at (370,262) rotate(-12)? Eh. Let me place \"Ribble\" at (352,300) rotate(-18) and Mersey at (362,350) rotate(4).\n- Lune: (330,235) rotate(70)? Lune flows S then W: label at (332,232) rotate(72)? Hmm near Lancaster (320,248). Put \"Lune\" at (338,225) rotate(70).\n- Wye: label at (350,530) rotate(75)? Wye flows S from Hereford: at (355,525) rotate(-70)? Hereford (329,500), Ross (342,519): direction SE then S. Label \"River Wye\" at (355,515) rotate(70).\n- Avon (Bristol): (385,600) rotate(-8) \"River Avon\" below Bath? Bath (364,592). Label at (385,605).\n- Exe: (235,650) rotate(75) \"River Exe\".\n- Tamar: (160,690) rotate(75) \"River Tamar\".\n- Dart: (215,715) rotate(40)? skip label? \"Dart\" small at (205,700) rotate(55)? Include small.\n- Medway: (640,630) rotate(-20) \"River Medway\".\n- Test/Itchen: skip labels (small). Or \"Itchen\" tiny. Skip.\n- Stour (Dorset): (390,665) rotate(20)? \"Stour\" small at (395,668)? Include tiny label.\n- Welland: skip label.\n- Soar: skip.\n- Cam: skip.\n- Teme: skip label? maybe tiny \"Teme\" at (345,470) rotate(15). Skip.\n- Warwickshire Avon: skip label.\n\nAlso label water bodies (sea): \"North Sea\" right side (700,250)? rotate(90)? Typically \"North Sea\" horizontal at (660,180)? East of England is North Sea: place at (690,200)? Hmm viewBox width 800: east coast x~775 at Lowestoft. North Sea label at (720,250)?? that's near Norfolk coast. Place \"NORTH SEA\" at (700,150)? Tyne mouth at (458,126); coast at that latitude ~ (450,112). (700,150) is over sea. OK. Or letter-spaced caps, light blue-gray.\n\"Irish Sea\" at (180,250)? West coast at lat ~54: x ~ 250-270. (180,250) over sea. OK.\n\"English Channel\" at (450,740)? South coast at lat 50.7: y ~ 670. (450,740) over sea. Hmm Land's End region: (250,760)? English Channel spans south: (480,745). OK.\n\"Bristol Channel\" at (230,640)? Between Wales and Devon: (240,635). Hmm Wales is at left; Bristol Channel label at (215,600)? Coast: Minehead (253,609), Ilfracombe (188,609) — channel is north of that line? The channel is between S Wales and N Devon: around (220,580)?? Wales coast (Swansea (-3.95,51.62): (205,555)). I won't draw Wales, but label \"Bristol Channel\" at (225,585) rotated slightly. OK.\n\"The Wash\" label at (660,400)? The Wash center around (620,390) is land?? No—the Wash polygon: coast routes around it, so interior (620,395) is sea. Label \"The Wash\" at (655,375)? Hmm Skegness (634,363), Hunstanton (649,388): interior point (640,378)? Wait the coast: Hunstanton (649,388) -> King's Lynn (639,413) -> ... -> Skegness (634,363). Interior of Wash ~ (630,385)? that's inside sea region? The polygon boundary goes around the Wash, so the Wash area is OUTSIDE the land polygon = sea colored. Point (630,385): is it west of the Skegness-King's Lynn lines? The coast segments: (632,366)->(634,363) Skegness and before that (620,372),(610,380),(602,390),(605,398),(615,408),(628,414),(639,413). So the inner coast is around x 602-639, and open sea to the east. Wash center ~ (627,388). Label at (660,385)? that's near Skegness-Hunstanton line (x 634-649) — east of it is sea. Put \"The Wash\" at (665,380) small italic? OK.\n\"Thames Estuary\"? skip. \"Humber\" — label the estuary: \"Humber\" at (575,305) rotate(-6) italic. Yes include since Humber is a major waterway (estuary).\n\"Solway Firth\" at (300,115)? skip? maybe small at (305,112)? Border area; skip.\n\"Morecambe Bay\" small at (320,235)?? that's near Lune mouth; skip? Morecambe Bay interior ~ (300,250)? Coast: (277,242)->(290,248)->(305,252)->(302,260)->(298,266): interior sea at (292,256)? Label \"Morecambe Bay\" tiny at (285,245)? Might collide. Skip.\n\"Spurn Head\"? skip.\n\nScotland label: \"SCOTLAND\" at (350,60)? above border. Wales: \"WALES\" at (220,480)? Wales is west: at lat 52, border x ~ 295-285. Wales label at (215,470) rotate(-90)? or horizontal (215,475). Place \"WALES\" at (215,460)?? Hmm that might overlap Bristol Channel. Wales spans lat 51.5-53.3: y from 571 to 343. Put \"WALES\" at (225,455) rotate(-80)? Let me just place horizontal at (215,440). Eh, fine.\n\nAlso \"Isle of Wight\" label tiny? skip.\n\nLegend (bottom-left or bottom-right box):\n- Blue line: River\n- Dashed: Canal\n- Dashed gray: National border\n- Blue italic: Water body\n- Dot: City\nPut legend bottom-left at (30, 830)? Depends on viewBox height. Let me set viewBox: coordinates range x 28-775, y 29-768. Add margins: viewBox=\"0 0 820 830\"? x max 775+margin=800; y max 768+margin=790; plus title space at top? Title can be HTML above SVG, or inside SVG. Let me put title inside SVG at top? The map top is Berwick y=29. If viewBox starts y=0, little room. I'll make viewBox=\"0 0 820 840\" and shift? Simpler: keep viewBox=\"0 0 820 800\", title as HTML heading above the SVG, legend as an SVG group bottom-left (10,690)? Bottom-left is over the Atlantic/Celtic Sea near Cornwall (Land's End (28,753), Lizard (80,768))... bottom-left corner (0-150, 700-800) is sea. Legend box there works: x 8-200, y 640-790? Actually Land's End x=28 — legend would overlap Cornwall's tip? Cornwall points: (92,709),(52,736),(28,753),(45,747),(80,768),(93,744)... Legend box from x=110 to 300, y=700-790? That covers sea SW of Cornwall? Points near: (136,721) Fowey, (155,718), (186,716) Plymouth... those are land/coast. Sea below y~730 from x 100-300: yes mostly sea (Plymouth coast at y~716-726, so y>735 is sea there). Legend at (105,735) size 260x60? Two-row legend. Hmm, alternatively place legend in the North Sea bottom-right: (600,700)-(800,790) — that's sea (Kent coast at y~590-650; sea below). Bottom-right corner: yes sea. Legend bottom-right at (585,705), 225x85. \n\nCompass rose: top-right over North Sea at (730,80)? North Sea at top-right: coast at (428,51),(400,29); sea to the east. (720,70) fine. Draw simple compass: circle + N arrow.\n\nTitle: HTML

+ subtitle. Also could be inside SVG; HTML is easier for styling.\n\nScale bar? Nice touch: bottom-right near legend: \"0 — 50 — 100 km\". Scale: x scale = 100 px per degree lon * 68 km/deg(at 52.5°) ≈ 0.68 km/px?? So 100 km ≈ 147 px. Hmm at latitude 52.5, 1° lon = 111.32cos(52.5)=67.7 km. So px per km = 100/67.7 = 1.477. 100 km = 148 px. Scale bar: 0 to 100 km, ticks at 50. Draw in legend area. y scale: 127 px per degree lat; 1° lat = 111.2 km → 1.143 px/km. There's projection distortion (x stretched 1.477 vs y 1.143) — typical equirectangular. The map will look slightly wide; acceptable, or I could adjust. Actually to reduce distortion I chose 127 vs 100 — ratio 1.27 vs true ratio (111.2/67.7)=1.64?? Hmm: for conformal look, pixels per degree lat / pixels per degree lon should equal (km per deg lat)/(km per deg lon) = 111.2/67.7 = 1.643. I used 127/100=1.27 — that makes England look wider/squatter than reality. Let me increase y-scale to 150: then ratio 1.5, closer. Or reduce x-scale to 80: 127/80=1.59 ≈ good. Let me recompute all coordinates with x=(lon+6)80, y=(56-lat)127? Then max x: 1.75+6=7.7580=620; y max (56-49.96)=6.04127=767. Width 620, height 767 — tall map. Alternatively y=(56-lat)131, x=(lon+6)80: ratio 1.64 exactly. y max = 6.04131=791. viewBox ~ 0 0 660 830.\n\nHmm, recomputing everything by hand is error-prone but doable — better: compute coordinates in JavaScript! I'll define all features as [lon, lat] arrays and project via JS function. That's much cleaner and lets me tweak scales easily. The SVG structure: script generates paths and appends. \n\nBut some might prefer pure static SVG... The user said \"Using svg tools draw me a map\" — an SVG map; generating with JS is fine and renders in browser. I'll do JS-generated for accuracy, with careful structure.\n\nPlan:\n- index.html style page: header with title, subtitle; main SVG; footer note.\n- JS: \n const proj = ([lon,lat]) => [ (lon - lon0)sx, (lat0 - lat)sy ] with lon0=-6.2, lat0=56.2, sx=80, sy=131.\n Let me set lon0=-6.2, lat0=56.3: x=(lon+6.2)80 → Land's End (-5.72): 38; Lowestoft (1.75): 636. y=(56.3-lat)131 → Berwick (55.77): 69; Lizard (49.96): 831. Hmm tall: viewBox 0 0 700 880? Let me compute ranges: x from 38 to 636 (plus labels), y 69 to 831. viewBox=\"-10 0 720 900\"? I'll add margins: viewBox=\"0 0 720 910\", and shift everything by +30 x? Use transform on a root group: translate(20,10). Fine-tune later.\n\n Helper: smoothPath(points) using Catmull-Rom → cubic bezier; returns path d string. For closed shapes (coastline) use closed Catmull-Rom with Z.\n\n- Draw order:\n 1. Sea rect with gradient + subtle wave pattern? Keep simple: gradient.\n 2. Graticule lines (light, every 1°) — nice cartographic touch, very light.\n 3. England land polygon (fill #f2ead8 parchment, stroke #8a9a7b or coastline stroke #6b8e6f?). Actually classic: land fill #faf3e3, coastline stroke #7c9a6d? I'll pick elegant muted: fill #f6efe0, stroke #9aa58c.\n 4. Isle of Wight polygon.\n 5. Borders (Scotland, Wales): dashed gray lines over land — but border lines coincide with coastline path segments (Berwick→Gretna; Chester→Chepstow). I'll draw separate dashed polylines slightly on the land side? Just draw along same points with dashed stroke — acceptable.\n 6. Canals (dashed teal/gray-blue).\n 7. Rivers (solid blue, varying width; two-pass: casing wider lighter, core darker).\n 8. Estuary widening: for Thames/Humber/Severn/Wash mouths, draw additional wide translucent strokes along lower reaches.\n 9. City dots + labels.\n 10. River labels (italic).\n 11. Sea labels (letterspaced).\n 12. Neighbor labels SCOTLAND/WALES.\n 13. Compass rose, scale bar, legend.\n\nFonts: use Google Fonts? External libraries need full tags — I can include to Google Fonts (allowed, must include full HTML). Use 'Cormorant Garamond' or 'EB Garamond' for labels and 'Marcellus'? I'll use system serif fallback plus Google font link: EB Garamond + maybe 'Poppins' for city names? Classic maps: cities in small caps sans or serif. I'll use: titles/labels serif (EB Garamond), city names also EB Garamond small caps-ish.

Let me compute screen coords after projection in JS anyway — but rotation needs to look right. I'll specify label positions in lon/lat and rotation manually tuned. Since I can't preview, choose sensible rotations:\n - Thames: pos (-0.85, 51.6), rotate -12 → hmm the stretch Reading→Windsor goes ENE: on screen, east-northeast with y-scale 131: direction vector from Reading (-0.98,51.45) to Henley (-0.9,51.53): dx=0.0880=6.4, dy=-0.08131=-10.5 → angle atan2(-10.5,6.4) ≈ -59°. Steep! Between Windsor→London: (-0.6,51.48)→(-0.13,51.5): dx=37.6, dy=-2.6 → ~-4°. So lower Thames is horizontal. Put \"River Thames\" label at (-0.35,51.52)? that's near Kingston-London; but London label at (-0.13,51.51) nearby. Put Thames label at (-0.55,51.55) rotate -6? Windsor at (-0.6,51.48)... place at (-0.5,51.57) rotate -8. Hmm Staines area. OK: pos (-0.5,51.58), rotate -5.\n Actually better: label \"Thames\" along Oxford-Reading reach: Oxford (-1.26,51.75) → Wallingford (-1.12,51.6): dx=11.2, dy=19.7 → angle 60° (steep down). Label rotate 60 at (-1.32,51.66)? near Oxford label... I'll go with lower Thames horizontal label at (-0.45,51.56) rotate -4, text \"River Thames\".\n- Severn: reach Shrewsbury→Worcester: (-2.75,52.71)→(-2.22,52.19): dx=42.4, dy=68.1 → angle 58°. Label at (-2.5,52.4) rotate 58? That's Ironbridge-Bewdley. Place pos (-2.42,52.42) rotate 62, \"River Severn\".\n- Trent: reach Newark→Gainsborough: (-0.81,53.08)→(-0.77,53.4): dx=3.2, dy=-41.9 → angle -86° (nearly vertical, going up). Label rotate -86 at (-0.72,53.25)? place east of river: pos (-0.68,53.25) rotate -88, \"River Trent\". Vertical text. OK.\n- Great Ouse: reach Bedford→St Neots: (-0.47,52.14)→(-0.27,52.23): dx=16, dy=-11.8 → -36°. Label at (-0.5,52.22) rotate -30, \"River Great Ouse\"? text \"Great Ouse\".

Place east of river.\n- Swale: skip label? \"Swale\" tiny at (-1.65,54.42) rotate -10? Include small? Skip.\n- Aire: reach Keighley→Leeds: (-1.91,53.87)→(-1.55,53.8): dx=28.8, dy=9.2 → 18°.

Label (-1.72,54.74) rotate -55, \"Wear\".\n- Tees: reach Barnard Castle→Darlington: (-1.92,54.54)→(-1.55,54.52): dx=29.6, dy=2.6 → 5°. Label (-1.75,54.58) rotate 4, \"Tees\".\n- Eden: reach Penrith→Carlisle: (-2.75,54.66)→(-2.94,54.89): dx=-15.2, dy=-30 → atan2(-30,-15.2) → 180+63= -117 → equivalently 63 reversed: text along NW direction: rotate -63? Text should read uphill-left; standard: rotate = angle of direction, flipping if >90. Direction angle = atan2(-30, -15.2) = -116.8° → normalize to 63° (flip text) → label rotate 63? That reads from Carlisle side... Cartographically fine. Use rotate -63 with text on the other side: pos (-2.82,54.78) rotate -63. Reading direction NW. OK choose -63.\n- Lune: reach Kirkby Lonsdale→Lancaster: (-2.6,54.2)→(-2.8,54.05): dx=-16, dy=19.7 → angle atan2(19.7,-16)=129° → flip -51°. Label (-2.5,54.14) rotate 55? Let me just place \"Lune\" at (-2.55,54.18) rotate 72?? Ugh. Simplify: place \"Lune\" near Lancaster at (-2.72,54.1) rotate 60. It'll look fine.\n- Ribble: reach Settle→Clitheroe: (-2.28,54.07)→(-2.39,53.87): dx=-8.8, dy=26.2 → 108.5 → flip -71.5. Label (-2.3,53.98) rotate 70, \"Ribble\".\n- Mersey: reach Warrington→Runcorn: (-2.6,53.39)→(-2.76,53.34): dx=-12.8, dy=6.6 → 153° → flip -27°. Label (-2.68,53.44) rotate -10? Place above estuary horizontal: (-2.7,53.43) rotate -8, \"Mersey\".\n- Dee: skip label? tiny \"Dee\" at (-3.0,53.26) rotate -30.

Label (0.38,51.3) rotate -20, \"Medway\".\n- Stour (Dorset): (-2.1,50.88) rotate 20, \"Stour\" small.\n- Humber: ( -0.45,53.76 )? estuary center (-0.45,53.71); label above estuary: pos (-0.45,53.77) rotate -2, \"Humber\" italic. Hmm Hull label at (-0.33,53.74) above — collision. Hull label move to above-right; Humber label at (-0.55,53.76). OK.\n- Thames estuary? skip.\n- Morecambe Bay: skip?

Hunstanton (0.49,52.95), Skegness (0.34,53.15): point (0.35,52.95) is inside Wash? The inner coast goes King's Lynn (0.39,52.75) → west side → Gibraltar Pt (0.32,53.1). Interior point (0.33,52.93) — likely just inside sea area. OK label at (0.36,52.95) rotate 0? Might overlap coast. Put at (0.45,53.0) rotate 0.\n- Solway Firth: (-3.15,54.86)? label at (-3.2,54.85) rotate 0 small? Near Eden mouth. skip? Include small \"Solway Firth\" at (-3.2,54.82)? Might clutter with Carlisle label. Skip.\n\nSea labels (letterspaced caps, fill #7ca6c4 or similar):\n- \"NORTH SEA\" at (1.1,54.4)? Screen: x=(1.1+6.2)80=584, y=(56.3-54.4)131=249. Coast at lat 54.4 ~ Whitby x=-0.6→(448). So (584,249) is sea. But Lowestoft coast x=636... label at lon 1.1, lat 54.4 fine. Maybe rotate 0. Or two words stacked.

Compass at (630,110) safe. Also \"SCOTLAND\" label at (284,115) top-center-left. Fine.\n\nScale bar in legend area: 100 km. At lat 53: px/km x = 80/(111.32cos53°) = 80/67 = 1.194. 100 km ≈ 119 px. I'll draw 0-50-100 km bar ~120 px inside legend.\n\nNow, graticule: vertical lines at integer lon from -6 to 2, horizontal at integer lat 50-56, light stroke rgba(0,60,120,0.08), with small edge tick labels? Tick labels add authenticity: label lat on left, lon on bottom, tiny gray. Maybe skip labels, keep lines. I'll add subtle lines only.\n\nSmoothing: implement Catmull-Rom → Bezier:\nfunction smoothPath(pts, closed=false). For open paths: standard.\n\nFor the coastline (closed), wrap around.\n\nRiver drawing: two strokes: casing (wider, #bcd8ea? opacity) and core (#4f8fbf). Widths vary: major (Thames, Severn, Trent, Gt Ouse, Yorkshire Ouse, Humber, Mersey, Tyne) core 2.6; medium 2.0; small 1.5. Estuary extra: draw a wider translucent stroke (e.g., 8px, opacity 0.35, same blue) on last segment? Simpler: add separate \"estuary glow\" paths: Thames lower (London→sea) width 9 opacity .3; Humber full width 10 opacity .3; Severn lower width 8; Wash big polygon? The Wash is already sea via coastline routing. Mersey lower width 8; Dee lower skip; Southampton Water? coastline routes handle it. Plymouth Sound? coast handles. Actually since coastline routes around estuaries (Thames to Gravesend/Tilbury, Humber to Trent Falls, Wash around, Dee to Chester, Southampton Water, Morecambe), the estuary shapes are already sea-colored — great, no extra work needed except maybe a short wide stroke connecting river end to estuary. Good.\n\nCanal style: stroke #7a9aad, width 1.4, dash \"5 3\", opacity 0.9.\n\nBorders: stroke #9b9b8a, width 1.2, dash \"6 4\". Draw along border point arrays (subset of coast): Scotland border array (8 points), Wales border array (16 points) — draw as open smooth paths.\n\nLabels styling:\n- River labels: font italic, fill #2f6d9e, size 12-14, letter-spacing 0.5.\n- Sea labels: fill #6d9cbd, size 15, letter-spacing 4, non-italic caps? Use small italic? Classic: caps italic light. I'll do normal (non-italic) caps, letterspacing 4, opacity .8.\n- City: fill #333, size 11.5, non-italic, with dot.\n- Country (SCOTLAND/WALES): fill #8a8a7a, size 13, letterspacing 3.\n- London: size 14 bold-ish.\n\nCompass rose: at (635,105): circle r 22 stroke, star polygon N pointer, \"N\" label. Draw simple elegant: two triangles (N/S) + E/W small, in #6d9cbd/#333.\n\nTitle block: HTML above SVG: \"Major Waterways of England\" big serif, subtitle \"Principal rivers, estuaries & canals\". Ornament line.\n\nAlso small note bottom: \"Stylised map — not to scale\"? The scale bar exists; say \"Schematic representation\".\n\nFrame: SVG has a decorative border rect (double border): outer rect stroke #8a9a7b, inner offset.\n\nLet me also double check projection extremes with lon0=6.2 offset, lat0=56.3, sx=80, sy=131:\n- Min x: Land's End -5.72 → (0.48)80=38.4. St Ives -5.48→57.6. Min label maybe Tamar source -4.52. So x min ~38. Add left margin: viewBox x from -20? Or shift all +? I'll set viewBox=\"-30 -20 760 930\"? Compute y max: Lizard 830.5; English Channel label at 788; legend box to y ~870 if placed at 790 height 80 → 870. Compass y 83-127 fine. SCOTLAND at 115. Berwick 69. Title inside? I'll put title in HTML, so top margin small: viewBox y from 40? Actually graticule from lat 56: y=(0.3)131=39. Top border near y 40-69. Let viewBox = \"-25 30 745 870\" → y range 30-900. Hmm legend bottom 870 → fits within 900. x range: -25 to 720: east label to 690 ok.\n\nLet me now also decide the Humber \"river\" path: I have coast routing up the Humber; the Humber label sits on estuary. Also draw a short wide blue line along Humber from Trent Falls to Hull to emphasize? The coast already outlines it as sea. Skip.\n\nAlso draw River Hull? skip.\n\nCheck Norwich label: Norwich (1.3,52.63) → x=600, y=(56.3-52.63)131=480.8. Label right → 605-650. Coast at Cromer (1.3,52.93): y=441. Norwich inland. River Wensum not drawn; fine.\n\nCambridge (0.12,52.2) → x=506.4?? wait x=(0.12+6.2)80=505.6, y=(56.3-52.2)131=537.1. Hmm! Earlier I computed Cambridge (612,484) with old scale. New scale: x=505.6, y=537. And Ely (0.26,52.4) → x=517, y=511. King's Lynn (0.39,52.75) → x=527.2, y=465.8. Coast Hunstanton (0.49,52.95) → x=535.2, y=439.6. OK.\n\nLondon → x=(−0.13+6.2)80=485.6, y=(56.3−51.5)131=628.8.\n\nBirmingham (-1.9,52.48) → x=344, y=500.4.\nManchester (-2.24,53.48) → x=316.8, y=369.4.\nLiverpool (-2.99,53.43) → x=256.8, y=376.\nLeeds (-1.55,53.8) → x=372, y=327.5.\nSheffield (-1.47,53.38) → x=378.4, y=382.5.\nNewcastle (-1.61,54.97) → x=367.2, y=174.2.\nBristol (-2.59,51.45) → x=288.8, y=637.2.\nNottingham (-1.15,52.95) → x=404, y=439.\nYork (-1.08,53.96) → x=409.6, y=305.6.\nHull (-0.33,53.74) → x=469.6, y=335.4.\nSouthampton (-1.37,50.9) → x=386.4, y=707.4.\nExeter (-3.53,50.72) → x=213.6, y=731.\nPlymouth (-4.14,50.37) → x=164.8, y=776.6.\nCarlisle (-2.94,54.89) → x=260.8, y=184.7.\nGloucester (-2.24,51.86) → x=316.8, y=581.6.\nOxford (-1.26,51.75) → x=395.2, y=596.\n\nCoast extremes new scale: Berwick x=336, y=69; Lowestoft x=(1.75+6.2)80=636, y=(56.3-52.48)131=500.4; Lizard x=(-5.2+6.2)80=80, y=830.5; Land's End x=38.4,y=817.5. Aldeburgh x=(1.6+6.2)80=624. Margate x=(1.38+6.2)80=606.4,y=(56.3-51.39)131=643.2.\n\nCompass at (640,120)? East of Berwick coast x336 — plenty sea. But Lowestoft coast x=636, Aldeburgh 624... compass at (645,120): near nothing (coast at that latitude ~ x 380-460). Fine. North Sea label at (584,249) → text spans ~584-700? Center at x 620: lon = 620/80-6.2=1.55. pos (1.55,54.5)? y=(56.3-54.5)131=235.8. Hmm Aldeburgh coast x=624,y=(56.3-52.15)131=543 — different latitude, fine. \"NORTH SEA\" centered at (615,240). But graticule... fine.\n\nIRISH SEA center: (200,330) → lon=(200/80)-6.2=-3.7, lat=56.3-330/131=53.78. pos (-3.7,53.78).\n\nENGLISH CHANNEL center (380,790) → lon -1.45, lat 50.27.\n\nBRISTOL CHANNEL center (210,650) → lon -3.575, lat 51.34. Hmm Minehead coast x=222.4,y=(56.3-51.21)131=666.8. Label at y 650 above Minehead — but Wales isn't drawn; region (150-280, 620-670): the land polygon edge from Ilfracombe (166,667)→Hartland...→ Minehead (222,667) is south boundary; above it (y<667) is outside polygon = sea. Good, label fits at y~645.\n\nLegend bottom-right: rect from (500,795) to (700,880)? Lowestoft x=636 y=500 — far. Kent coast Margate y=643. Bottom right area y>700: sea. But \"Deal\" coast x=(1.4+6.2)80=608, y=(56.3-51.22)131=665.5. So legend at (505,790)-(705,875): all sea? The polygon's SE corner near (606-611, 643-666) — yes y>700 is sea. \n\nScale bar inside legend: from x 520 to 640 (120px ≈ 100 km at lat 53). Ticks at 0, 60, 120 → labels 0, 50, 100 km.\n\nWait, also need \"The Wash\" label: pos (0.45,53.0) → x=532, y=432. Hunstanton x=535,y=439.6; Skegness x=(-0.66?no (0.34+6.2)80=523.2, y=(56.3-53.15)131=412.7. Coast inner: King's Lynn x=527,y=466. Interior of Wash ~ (515,440)? Label \"The Wash\" centered (510,432)? Hmm Gibraltar Pt x=(0.32+6.2)80=521.6,y=424. Put label at (500,440) center, rotate 0. Check coast: inner Wash west side points: (0.25,52.77) x=516,y=463; (0.1,52.83) x=504,y=455.5; (-0.02,52.97) x=478.4,y=437.3 — wait that point is the SW corner of the Wash (Boston corner) at x=478. Hmm so Wash interior around (490-520, 430-460). Label at (500,442) OK. But wait — is (-0.02,52.97) on the coast? Boston is inland; the Wash corner around (0.0,52.95)? The actual SW corner of the Wash near Gedney Drove End ~ (0.05,52.85)? Let me use points: King's Lynn (0.39,52.75) → (0.25,52.78) → (0.1,52.87) → (0.05,52.97) → (0.15,53.05) → (0.32,53.1) Gibraltar Pt → Skegness. OK.\n\nNow Witham mouth: Boston (-0.02,52.97) → x=478,y=437 — right at Wash corner. Good.\n\nAlso Humber routing points: Cleethorpes (-0.05,53.56) x=476,y=359.6; Grimsby (-0.08,53.57) x=473.6,y=358.3; Immingham (-0.2,53.62) x=464,y=354.6; (-0.32,53.66) x=454.4,y=350.5; (-0.45,53.68) x=444,y=348.6; (-0.55,53.7) x=436,y=346; Trent Falls (-0.69,53.7) x=424.8,y=346; north bank: (-0.6,53.72) x=432,y=343.4; (-0.45,53.73) x=444,y=342; Hull (-0.33,53.74) x=453.6?? wait Hull x=(−0.33+6.2)80=469.6. Hmm I mislisted: (-0.45,53.73) x=444 — that's west of Hull (469). Order from Trent Falls eastward: (-0.6,53.72) 432 → (-0.5,53.73) 440 → (-0.42,53.73) 446.4 → Hull (-0.33,53.74) 469.6 → (-0.2,53.72) 464?? no: (-0.2+6.2)80=480. → (-0.05,53.68) 476?? (0.05? ) (-0.05+6.2)80=492, y=(56.3-53.68)131=344.2 → Spurn (0.15,53.58) x=508,y=358.3 → then back north (0.1,53.65) x=504,y=349.2 → Withernsea (0.03,53.72) x=498.4,y=341.1 → Hornsea (-0.05? no Hornsea (-0.17,53.91)) → Bridlington (-0.19,54.08) x=464.8,y=291.5 → Flamborough (-0.08,54.12) x=473.6,y=286.2 → Filey (-0.29,54.21) x=456.8,y=274.5 → Scarborough (-0.4,54.28) x=448,y=265.3 → Whitby (-0.6,54.48) x=432,y=239.2 → ...\n\nHumber label at (-0.5,53.78) → x=456, y=329.5. Hull city label at (469.6,335) → put Hull label above dot: (469.6, 328)? Humber label then at (430,330)? Let me: Humber label centered (430,331) rotate 0 italic; Hull dot (469.6,335.4) label \"Hull\" above (469.6, 327). Slight collision risk w/ estuary line y~342-346. Labels at 327-331 fine.\n\nYork (409.6,305.6) label right: (416,309). Ouse river passes through York; label \"Ouse\" at (-1.0,53.86) → x=416,y=321.7 — collision with York label! Move Ouse label to (-0.98,53.83) → x=417.6,y=325.6 — still near. Instead put Ouse label west of river at (-1.16,53.85) → x=403.2,y=323, rotate 82. York label right at (417,308). OK distance ~15px fine.\n\nAire label at (-1.78,53.9) → x=353.6,y=313.7 rotate 14. Leeds label above dot (372,327.5-7=320). Fine.\n\nWharfe label small at (-1.5,53.96) → x=376,y=306.5 rotate 8. Hmm near York label (417,308) no. OK.\n\nSwale label tiny at (-1.6,54.44) → x=368,y=244? rotate -6. Might skip. I'll include \"Swale\" small at (-1.62,54.45)→(366.4,242.7) rotate -8. Eh — near Tees label? Tees label at (-1.75,54.58) → x=356,y=225.4. OK separate.\n\nTees label at (356,225) rotate 4 \"Tees\". Darlington area. Wear label at (-1.72,54.76) → x=358.4,y=201.6 rotate -58? Wear direction Bishop Auckland→Durham computed -63°. pos (-1.74,54.74) x=356.8,y=204.2 rotate -60 \"Wear\". Tyne label at (-1.9,55.0) → x=344,y=170.6 rotate 0 \"Tyne\". Newcastle label above dot (367.2,174.2): \"Newcastle\" at (367,166) anchor middle — collides Tyne label at y170 x344? Tyne label spans x~332-356 (center 344). Newcastle label spans ~340-394 center 367 at y166. Slight vertical overlap (166 vs 170) — move Tyne label to y 177 below river: pos (-1.9,54.94) → y=178.2. But river at y~174; label below river at 182? Wear label at 204 nearby but x 357-370... Tyne label center (344,183): spans 332-356. Newcastle city at (367,174). OK set Tyne label pos (-1.92,54.93) → x=342.4,y=179.6, rotate 0. Hmm Wear label at (356.8,204) fine.\n\nEden label at (-2.84,54.8) → x=268.8,y=196.8 rotate -63. Carlisle label above dot (260.8,184.7): at (261,177) middle. Eden label spans near (269,197) rotated — ok.\n\nLune label at (-2.55,54.14) → x=292,y=283.4?? lat 54.14 → y=(56.3-54.14)131=282.96. Hmm that's not near Lancaster (Lancaster (-2.8,54.05) → x=272,y=294.9). Lune river: Kirkby Lonsdale (-2.6,54.2) → x=288,y=275.1; Hornby (-2.64,54.11) x=284.8,y=286.6; Lancaster (272,294.9); mouth (-2.92,53.97) x=262.4,y=305.4. Label \"Lune\" at (292,268)? pos (-2.55,54.25) → x=292,y=268.5 rotate 65. OK.\n\nRibble label at (-2.3,53.98) → x=312,y=304.2?

Label \"Ribble\" at (-2.35,54.02) → x=308,y=299.5 rotate 72. Hmm near Lune label (292,268)? fine.\n\nMersey label at (-2.7,53.45) → x=280,y=373.4?? Liverpool label at (256.8,376-7=369) middle → spans ~228-286?? \"Liverpool\" ~55px → 229-285. Mersey label at (280,373) collides! Move Mersey label east: pos (-2.6,53.45) → x=288,y=373.4... Liverpool label anchor middle at (256.8,369): ends at ~285. Collision. Put Mersey label below river: pos (-2.62,53.36) → x=286.4,y=385.2 rotate -6. Warrington (x=(-2.6+6.2)80=288,y=(56.3-53.39)131=381). Hmm river y ~381-386 there. Label at 385 ON river. Put Mersey label at (-2.5,53.44) → x=296,y=374.7 rotate -5, spans 280-312? \"Mersey\" ~42px → 275-317 center 296. Liverpool label ends 285. OK-ish gap 10px...

Collides Liverpool label (229-285 at 368)?! Yes collision. Move Manchester label above-right: anchor start at (322,362)? Irwell river near. Or Manchester label right: (323,373) anchor start — collides Mersey label (275-317 at 374.7)? starts 323 > 317 OK gap 6px. Hmm tight but OK. Actually Mersey label center 296 span 275-317 y~375; Manchester label at (323,373) start → spans 323-385. Sheffield label: Sheffield dot (378.4,382.5) label right (385,386): spans 385-435. Manchester ends 385 — collision with Sheffield start! Move Sheffield label below dot: (378,394) middle? spans 353-403 at y394. Manchester label y373. OK. And Trent/Mersey canal passes y~?

Aire label at (353.6,313.7) spans 340-367 rotate 14 — near Leeds label (350-394 at 320)? 6px gap. Move Aire label west: pos (-1.85,53.88) → x=348,y=315.8... same. Move Leeds label right of dot: (379,331) start spans 379-423? York label at (417,308) — different y. OK Leeds label right: x 379-423 at y331. Aire label at (348,316). Good. Leeds-Liverpool canal near... fine.\n\nSheffield (378.4,382.5) label below middle (378,394). Nottingham (404,439) label above middle (404,431) spans ~375-433. Soar river from Leicester (-1.14,52.63) x=404.8,y=481.7 → joins Trent (-1.28,52.86) x=393.6,y=451.6. Nottingham label at 431 vs Soar at 451+ fine.\n\nBirmingham (344,500.4) label left anchor end (337,504): spans ~277-337. Grand Union canal ends there. OK.\n\nBristol (288.8,637.2) label: left end anchor (282,641) spans ~245-282? Avon river below. Severn mouth at (x(-2.8,51.53)=272,y=645). Bristol label at (282,641)... near Avonmouth coast x(-2.72,51.5)=278.4,y=641.6!! Coast point right there. Move Bristol label above: (289,629) middle spans 265-313. Severn river end at (272,645),(262,649)? My Severn end [-2.85,51.52] → x=268,y=646. OK Bristol label at (289,629) fine.\n\nGloucester (316.8,581.6) label right (324,585) spans 324-380. Severn at Gloucester x(-2.24)=316.8 — label east of river OK. Wye label at (-2.62,52.0) → x=286.4,y=563.4 rotate 60. OK.\n\nOxford (395.2,596) label above (395,588) middle spans 375-415.

London dot (485.6,628.8) label right (493,632) spans 493-540. Thames label ends 490. OK tight. Move Thames label west: center (445,625) spans 405-485. Reading (x(-0.98)=417.6,y=(56.3-51.45)131=635.4) — Reading not labeled as city. OK Thames label center (448,624).\n\nCambridge label right of dot (505.6,537.1): (512,541) spans 512-570. Ely river at x 517,y511. Coast at Cromer x(1.3)=600... fine. Norwich label right (600,480.8): (607,485) spans 607-655. Coast at y~480: Aldeburgh (624,543)? no. Coast at lat 52.6: Gt Yarmouth x=(1.73+6.2)80=634.4,y=(56.3-52.6)131=484.7!! Norwich label spans 607-655 at y485 — crosses coast at 634! Coast east of Norwich label... The label would overlap coastline near Yarmouth. Shorten: Norwich label above dot: (600,472) middle spans 575-625. Coast at y472: lat = 56.3-472/131=52.7 → coast between Yarmouth (634,484.7) and Happisburgh (x(1.5)=616,y=459) → coast x at y472 ≈ 625. Label ends 625 — touching. Shift label left-anchor end: (593,472) spans 533-593. Fine — Norwich label left of dot.\n\nHmm wait, Cambridge label (512,541): Great Ouse river at Ely (517,511), Cam river through Cambridge. Label east of Cam. OK.\n\nSouthampton (386.4,707.4) label above (386,699) middle spans ~345-427. Itchen river ends (x(-1.37,50.9)=386.4,y=707.4). Test ends (x(-1.42,50.88)=382.4,y=710). Labels at 699 above rivers OK. Coast head of Soton Water (x(-1.31,50.85)=391.2,y=713.9). Label above fine.\n\nExeter (213.6,731) label right (220,735) spans 220-255. Exe river at Exeter x=213.6. Coast Exmouth (x(-3.42,50.62)=222.4,y=744.4). Label at 735 vs coast 744 OK.\n\nPlymouth (164.8,776.6) label above (165,768) middle spans ~135-195. Coast near Plymouth y~776. OK. Tamar label at (-4.28,50.55) → x=153.6,y=753.5 rotate 68. Dart label at (-3.8,50.44) → x=192,y=767.7 rotate 40 — near Plymouth label (135-195 at 768)!! Collision. Move Dart label NE: pos (-3.72,50.5) → x=198.4,y=759.6 rotate 45. Still near (195 end). Plymouth label spans 135-195 at y768; Dart label at (198,760) rotated — diagonal, probably OK. Or drop Dart label. I'll keep small \"Dart\" at (-3.68,50.47)→(201.6,763.7) rotate 45, size 10. Eh, risk. Alternatively move Plymouth label below-left into sea: (165,790)? Coast at Plymouth y 776-782; below is sea (sound). Label at (165,792) middle — sea, fine! Do that. Then Dart label at (198,760) fine.\n\nExe label at (-3.45,50.82) → x=220,y=720 rotate 78 — near Exeter label (220,735)? Exe label center (220,720) spans vertical ~700-740 rotated... collision with Exeter label at (220,735) horizontal! Move Exeter label left anchor end (207,735) spans 175-207. Exe label rotated at x~218-222 vertical band y 702-738 — near Exeter dot (213.6,731)?? dot at 213.6. Label band at 220 — hmm. Simplify: Exe label at (-3.42,50.78) → x=222.4,y=725.3 rotate 75; Exeter label left end at (207,735). OK.\n\nCarlisle (260.8,184.7) label above middle (261,176). Solway coast at (x(-3.05,54.9)=252,y=182.7)... label above fine.\n\nLondon (485.6,628.8) label right (494,633) \"London\" size 14 spans 494-545. Thames river continues east (x(0.02,51.5)=497.6,y=628.8)... label sits on river line. Move London label below-right? Standard: label right with dot on river — the river passes through; acceptable, or label above: (486,620) middle spans 455-517 — collides Thames label (405-485 at 624)?! Thames label ends 485, London starts 455 overlap. Fix: Thames label center (440,622) spans 400-480; London label right (494,633). River at y629: label at 633 slightly below line. OK.\n\nKingston/Staines area fine.\n\nWash label (500,442): Witham river end Boston (478,437)→mouth (0.05,52.9) x=480,y=433.9. Label \"The Wash\" italic center (505,445) spans 475-535. Nene mouth (0.2,52.85) x=512,y=454.7. Hmm label at 445 vs Nene end 454 OK. But is (505,445) inside Wash (sea)? Coast points: (0.1,52.87) x=504,y=461.5; (0.05,52.97) x=480,y=438.6; (0.15,53.05) x=508,y=426. So polygon edge passes near (504,461)-(480,438)-(508,426). Point (505,445): between edges... The sea region is EAST of these edges. Edge from (480,438) to (508,426): at x=505, edge y≈427. Point y=445 > 427 → inside?? The land is WEST of coast going north... traversing from King's Lynn northward to Skegness, land on left (west), sea right (east). Point (505,445): relative to edge (480,438)-(508,426), at x=505 the edge y=427.8; point y=445 is below → is below = west side? For edge going NE (up), west side is below-left... ugh. Simply: point (505,445) vs King's Lynn edge (527,466)→(516,463)→(504,461): at x 504-505, edge y 461. Point y=445 is ABOVE that edge (smaller y = north = sea side here since sea is north/east of Lynn). And vs Boston corner (480,438): point is east (x 505 > 480) → sea side. And vs (508,426): point y 445 > 426, but that edge goes to Gibraltar Pt (521.6,424)... point (505,445) is WEST of x=508 → hmm west of that edge = land?? The edge (480,438)→(508,426): for a point to be sea (east of this NE-going edge), it must be... take midpoint (494,432); sea is toward Skegness direction (NE/east): test point (520,432) is sea. Our point (505,445): cross product of edge vector (28,-12) with point vector (505-480,445-438)=(25,7): cross = 287 - (-12)25 = 196+300=496 >0 → point is to the left of edge direction (going from Lynn to Skegness). Left side when walking north-ish = west = LAND. So (505,445) is land! Move Wash label east: (530,440)? Gibraltar Pt x=521.6 y=424; Skegness (523.2,412.7). Edge Gibraltar→Skegness nearly vertical x~522. Point (530,440): east of x 522 → sea. But also edge (508,426)→(521.6,424): point (530,440) east → sea. OK \"The Wash\" center (538,438) spans 508-568? At 13px italic \"The Wash\" ~55px → spans 510-565. Hunstanton edge: (0.45,52.85) x=532,y=461; Hunstanton (535.2,439.6)!! Coast point AT (535,440) — collision! The Wash narrows: label between x 522-535 hard. Put label lower: center (535,455)? Coast (532,461),(516,463)... point (535,455): east of edge (504,461)→(532,461)?? that edge horizontal y~461 at x 504-532; point y 455 above → sea. And Hunstanton (535,439.6) 15px above. Label spans 507-563 at y455-460 — overlaps edge y461 barely. Hmm. Alternatively rotate label 90? Put \"The Wash\" vertical at (545,430) rotate -90? Vertical text along the Wash's east side... The Wash opens north. Actually simplest: place \"The Wash\" at (545,455) rotate 0 — spans 517-573, baseline 458; coast Hunstanton (535,439.6) is 18px above center — the text top ~445 → clear of 439.6? 6px gap. Skegness (523,412) far. Gibraltar edge x~522 at y424-427: text top 445 clear. OK: center (545,457)? spans y ~447-462; edge y461 at x 504-532 — text bottom 462 ~ touching at x 517-532. Nudge up: center (548,452) → bottom 457 > 461? no 457<461 fine. Set (548,450). Good enough; slight imprecision acceptable for stylized map.\n\nAlso Skegness-Hunstanton mouth line: not drawn (coast goes around Wash) — correct.\n\nMorecambe Bay label? skip (decided).\n\nSolway label skip.\n\nHumber: verify coast routing includes up-estuary points: after Mablethorpe (0.27,53.35) → (0.15,53.45) → Cleethorpes (-0.05,53.56) → hmm jump from 0.15 to -0.05 fine → Grimsby (-0.08,53.57) → Immingham (-0.2,53.62) → (-0.32,53.66) → (-0.45,53.68) → (-0.55,53.7) → Trent Falls (-0.69,53.7) → (-0.6,53.72) → (-0.5,53.73) → Hull (-0.33,53.74) → (-0.15,53.71) → (0.05,53.64) → Spurn (0.15,53.58) → (0.1,53.65) → Withernsea (0.03,53.72) → ... wait (0.1,53.65) x=504,y=349 then Withernsea (0.03,53.72) x=498.4,y=341 — going back west?? Withernsea lon 0.03 < 0.1 — yes coast curves back slightly; actual Spurn-to-Withernsea: Spurn (0.15,53.58) tip; mainland resumes ~ (0.1,53.62)? then Withernsea (0.03,53.72), Hornsea (-0.17,53.91). OK sequence: Spurn (0.15,53.58) → (0.12,53.63) → (0.05,53.7) → Withernsea (0.03,53.72)?? redundant; use Spurn → (0.1,53.64) → Withernsea (0.02,53.72) → (-0.08,53.83) → Hornsea (-0.17,53.91) → (-0.19,54.02) → Bridlington (-0.19,54.08) → Flamborough (-0.08,54.12) → Filey...\n\nAlso Thames coast routing: Sheerness (0.76,51.44) → (0.62,51.45) → (0.5,51.42) → Gravesend (0.37,51.44) → cross → Tilbury (0.45,51.48)? Hmm Tilbury (0.37,51.47)? Gravesend (0.37,51.44) south bank; Tilbury (0.36,51.47) north bank. Then east along north bank: (0.5,51.5) → (0.62,51.52) → Southend (0.71,51.54) → (0.85,51.6) → (1.0,51.7) → Clacton (1.15,51.79). Good.\n\nDee coast routing: Liverpool (-3.0,53.45) → Hoylake (-3.18,53.39) → (-3.13,53.31) → (-3.02,53.24) → Chester border start (-2.9,53.19). Good — estuary indent on England side.\n\nNow borders arrays:\nSCOT_BORDER: [-2.003,55.769],[-2.18,55.68],[-2.35,55.55],[-2.5,55.42],[-2.62,55.28],[-2.78,55.13],[-2.95,55.05],[-3.06,54.99]\nWALES_BORDER: [-2.9,53.19],[-2.95,53.1],[-2.99,53.05],[-2.9,52.95],[-3.05,52.86],[-3.0,52.75],[-3.14,52.66],[-3.08,52.5],[-3.05,52.35],[-3.15,52.2],[-3.13,52.07],[-3.0,52.0],[-2.95,51.93],[-2.85,51.87],[-2.72,51.81],[-2.67,51.64]\n\nCity marker style: circle r=2.6 fill #2b2b2b; London: r=3.4. Label font 11px, fill #2b2b2b.\n\nNow canal/river label for canals? Legend only. Maybe label \"Grand Union Canal\" along it tiny? Legend suffices.\n\nLegend content:\n- Title \"Legend\" small caps.\n- Line sample solid blue: \"River\"\n- Line sample dashed: \"Canal\"\n- Line sample dashed gray: \"Country border\"\n- Dot: \"Town / City\"\n- Scale bar: 0—50—100 km.\n\nAlso nice: a faint paper-texture background for whole page, and the SVG sea gradient. Add subtle inner shadow? Keep performance simple.\n\nCompass: at (648,115): circle r=20 stroke #7fa6c9 fill white opacity .7; N arrow polygon points up; \"N\" above. Simple elegant: vertical line with arrowhead, small circle center, cardinal letters N/E/S/W tiny? Just N + arrow + circle.\n\nGraticule labels: skip.\n\nOne more consideration: smoothing closed coastline with Catmull-Rom — must wrap points. Implement.\n\nRiver widths mapping:\n- major 3: Thames, Severn, Trent, Yorkshire Ouse, Great Ouse, Tyne, Mersey\n- medium 2.2: Wye, Aire, Wear, Tees, Eden, Nene, Witham, Exe, Tamar, Medway, Ribble, Lune, Bristol Avon, Welland, Swale, Wharfe\n- small 1.6: Warwickshire Avon, Teme, Soar, Cam, Dee, Dart, Stour Dorset, Hants Avon, Test, Itchen, Irwell, N/S Tyne branches\n\nCasing: width = core+1.8, color #d7e8f3.\n\nActually, let me reconsider colors for an elegant look:\n- Sea: linear gradient #cfe3ef → #bcd7e8, or radial? Use vertical gradient light.\n- Land: #f4ecd9 with stroke #a89f87 1px. Maybe add subtle inner glow via second stroke? Fine.\n- Rivers: core #3e7cb1, casing #c9e0ef.\n- River labels: #2e6da4 italic.\n- Sea labels: #5d8fb3, letterspacing 5.\n- Canals: #8aa5b5 dashed.\n- Borders: #a39d8c dashed.\n- Cities: #3a3a3a dots; labels #333.\n- Land labels (SCOTLAND/WALES): #96917f letterspacing 4.\n- Title HTML: #2c4a63 serif.\n\nPage: background #eef3f6 or parchment #f7f4ec? Sea is blue; page bg soft #e9eef2. Card with white border shadow around map.\n\nInclude Google Fonts link: EB Garamond (400,500,600 + italic). And maybe 'Cinzel' for title? Keep EB Garamond everywhere; title weight 600 letterspacing.\n\nStructure:\n\n

\n \n\n\nviewBox: x from -25 to 730? east extent ~690 (North Sea label ends ~690; Lowestoft 636 + ?). \"NORTH SEA\" centered (615,240) letterspacing: width ~ 9 chars* (13+5) ≈ 160 → spans 535-695. OK x max 700 → viewBox width 730 with -25 start → to 705. y: from 25? top content: SCOTLAND label y~115, coast min y 69, compass top ~90. Graticule top lat 56 → y=39.3. So start y=25 OK. Bottom: legend 795-875 → end 885. Height = 885-25=860. viewBox=\"-25 25 730 860\".\n\nHmm compass at (648,115): check North Sea label at (615,240) no clash. East coast near (1.75,52.48)=636,500. Compass fine.\n\nLegend at x 505-700, y 795-872: inside, items:\n- header \"LEGEND\" at (525,815) letterspaced.\n- river sample: line (520,832)-(560,832) core+casing; text (568,836) \"River\".\n- canal sample y 852: dashed (520,852)-(560,852); \"Canal\".\n- border sample y 872?? bottom limit 872 tight. Rearrange: two columns:\n Col1 x 515-610: River (y830), Canal (y850), Border (y870)\n Col2 x 615-700: City dot (y830), Scale bar (y855-865)\nLet me define legend rect (500,788) w 205 h 92 → bottom 880. viewBox bottom 890. Set viewBox=\"-25 25 730 870\" (y 25..895).\n\nHmm wait — is there sea at (500,788)? SE corner: Kent coast lowest point: Deal (608,665), Dover (732?? recompute: Dover (1.32,51.13) → x=(1.32+6.2)80=601.6,y=(56.3-51.13)131=677.3. So coast max y in SE ~ 680. Legend y>788 → sea. Yes fine. And Dungeness (0.98,50.91) → x=574.4,y=706.5 — still < 788. Good.\n\nAlso, south coast around Beachy Head y: (0.24,50.74) → y=728.4; Selsey (521?? x=(-0.79+6.2)80=432.8,y=(56.3-50.72)131=731). English Channel label at y~790 x 295-465. Legend starts x 500 — clear.\n\nLizard (80,830.5) bottom; Land's End (38.4,817.5). Bottom-left sea below Cornwall: could place scale bar there instead — no, keep in legend.\n\nNow compute remaining label screen positions for JS data (I'll store label positions in lon/lat too, with rotation):\n\nriverLabels = [\n {t:\"River Thames\", p:[-0.62,51.585], r:-5} → x=(-0.62+6.2)80=446.4,y=(56.3-51.585)131=617.7. center 446 — good matches earlier plan.\n {t:\"River Severn\", p:[-2.45,52.42], r:60} → x=300,y=568.4?? lat 52.42 → y=(3.88)131=508.3. x=(-2.45+6.2)80=300. Severn at lat 52.42 ~ x(-2.45)=300 — label ON river; offset east: p [-2.38,52.42] → x=305.6. rotate 60. OK p [-2.36,52.45] → x=307.2,y=504.4, r:62.\n {t:\"River Trent\", p:[-0.7,53.22], r:-85} → x=440,y=403.6?? lat 53.22 → y=(3.08)131=403.5. Trent river at lat 53.22: x(-0.8,53.2)=432. Label east x=440. OK p [-0.68,53.22] → x=441.6, r:-84.\n {t:\"Great Ouse\", p:[-0.52,52.2], r:-28} → x=454.4,y=536.9. Bedford label? Bedford not a city. OK.\n {t:\"Nene\", p:[-0.6,52.42], r:-40} → x=448,y=508.4.\n {t:\"Witham\", p:[-0.22,53.14], r:33} → x=478.4,y=413.3. Lincoln (x(-0.54)=452.8,y=419.6)? Lincoln not labeled. OK.\n {t:\"Ouse\", p:[-1.17,53.85], r:82} → x=402.4,y=324.5.\n {t:\"Aire\", p:[-1.83,53.9], r:13} → x=349.6,y=315.9.\n {t:\"Wharfe\", p:[-1.52,53.97], r:8, s:10} → x=374.4,y=308.7. Hmm York label at (417,308). OK.\n {t:\"Swale\", p:[-1.62,54.46], r:-8, s:10} → x=366.4,y=241.3.\n {t:\"Tyne\", p:[-1.93,54.92], r:0} → x=341.6,y=181.7.\n {t:\"Wear\", p:[-1.75,54.73], r:-60} → x=356,y=205.3.\n {t:\"Tees\", p:[-1.78,54.58], r:4} → x=353.6,y=226.6.\n {t:\"Eden\", p:[-2.83,54.8], r:-63} → x=269.6,y=196.1.\n {t:\"Lune\", p:[-2.55,54.26], r:65, s:11} → x=292,y=267.2.\n {t:\"Ribble\", p:[-2.36,54.03], r:72, s:11} → x=307.2,y=298.2.\n {t:\"Mersey\", p:[-2.52,53.45], r:-6} → x=294.4,y=374.7.\n {t:\"Dee\", p:[-3.0,53.27], r:-25, s:10} → x=256,y=377.3?? lat 53.27 → y=396.5. x=(-3+6.2)80=256. Dee estuary channel near (252-262, 390-400). p [-3.02,53.3] → x=254.4,y=392.6, r:-25. Near coast Hoylake (x(-3.18,53.39)=241.6,y=382.4). OK.\n {t:\"Wye\", p:[-2.6,52.0], r:60} → x=288,y=563.4.\n {t:\"Avon\", p:[-2.2,51.49], r:-22, s:11} → x=320,y=632.3?? lat 51.49 → y=(4.81)131=630.1. x=(-2.2+6.2)80=320. Hmm Bristol label at (289,629) spans 265-313. Avon label center 320 spans ~300-340 rotate -22 — near Bristol label end 313! Move Avon label south: p [-2.24,51.44] → x=316.8,y=636.7 — Bristol label y 629 spans to 313... diagonal. Move Avon label east toward Bath: p [-2.15,51.45] → x=324,y=635.4 rotate -15. Bath river bend. OK.\n {t:\"Exe\", p:[-3.43,50.8], r:75} → x=221.6,y=721.5.\n {t:\"Tamar\", p:[-4.3,50.56], r:66, s:11} → x=152,y=751.9.\n {t:\"Dart\", p:[-3.7,50.48], r:45, s:10} → x=200,y=762.4.\n {t:\"Medway\", p:[0.38,51.31], r:-18} → x=526.4,y=654.1?? lat 51.31 → y=(4.99)131=653.7. Maidstone (0.52,51.27) x=537.6,y=658.9. Medway river y ~ 654-662 there. Label above river: p [0.4,51.35] → x=528,y=648.5 rotate -18. OK.\n {t:\"Stour\", p:[-2.08,50.9], r:18, s:10} → x=329.6,y=707.1. Stour river at Blandford (-2.16,50.86) x=323.2,y=713.7. Label near. OK.\n {t:\"Humber\", p:[-0.52,53.78], r:-2} → x=454.4,y=329.5.\n {t:\"The Wash\", p:[0.5,52.98], r:0, s:11} → x=536,y=434.9?? computed earlier center (548,450)... p lon/lat [0.5,52.98] → x=536,y=434.9. Hunstanton coast (535.2,439.6)!! 5px below. Ugh. p [0.42,52.93] → x=529.6,y=441.1 — coast Hunstanton (535,439.6) 6px right. The Wash interior is tight on screen. Alternative: put \"The Wash\" INSIDE at p [0.28,52.92] → x=518.4,y=442.4? Coast inner west edge at that y: (0.15,53.05) x=508,y=426 → (0.05,52.97) x=480,y=438.6: at y 442, edge x ≈ 476. Sea east of 476: 518 OK. And mouth edge Hunstanton (535,439.6)→(532,461): at y 442 edge x≈534.5. So x 518 within sea (476-534). \"The Wash\" at 11px ~48px wide → center 518 spans 494-542 — crosses 534.5 edge slightly at bottom. Font 10: spans 496-540. Meh, slight overlap of coastline. Alternatively rotate -90 vertical at x 515: spans y 415-465 vertical... crosses west edge (x 476-508 at y 426-438)? At x=515 vertical line from y415-465: near Skegness edge x~522 at y 412-424 — clear; near Gibraltar (521.6,424) — x515 clear; bottom y465 near Lynn edges x 504-527 at y 461-466: x515 y465 → on edge?! Hmm. Compromise: place \"The Wash\" horizontally at p [0.33,52.88] → x=522.4,y=447.9, size 10, spans ~498-547 at baseline 448, top 438. West edge at y448: between (480,438.6) and (504,461) → x≈484. East edge at y448: (535,439.6)→(532,461) → x≈534.4. So sea spans 484-534 at y448. Text 498-547 exceeds east (534) by 13px — the word would cross coastline near Hunstanton. Sigh. Use size 9.5 and center 515: spans 493-537... still. OK final: two lines? \"The\" above \"Wash\"? Or place label offshore mouth: p [0.62,53.05] → x=545.6,y=425.9?? that's east of Skegness (523,412) and north of Hunstanton (535,439) → open sea! The Wash's mouth region. Place at (548,428) rotate 0 size 11 — represents The Wash at its mouth. Hmm, but geographically that's outside. For clarity, fine: p [0.65,53.02] → x=548,y=430.2.

Hmm south coast at lat ~50.2-50.3: y 817-831. Our label y 794 is NORTH of those (smaller y)?? No: y 794 < 817 → label is north of Lizard/Start Point latitude but that's far west/east. At x 278-474, coast y: Plymouth (164,776), Dartmouth (x(-3.58,50.35)=209.6,y=781.9), Torquay (x=214.4,y=774), Exmouth (222,744), Lyme (260.8,y=731.5)... at x 278-474 the coast y ranges 698-731 (Portland x=(-2.46+6.2)80=299.2,y=759.4; Lulworth x=316,y=744.5; Swanage x=340,y=744; Solent x 355-391,y 710-713; Portsmouth x=408,y=723.1; Selsey 432.8,731).

Swale label (366.4,241.3) rotate -8 size 10: Swale river Richmond (x(-1.74,54.4)=356.8,y=249.3) → (-1.6,54.37) x=368,y=253.2. Label at (366,241) — 10px above river. Tees label at (353.6,226.6) — clear (15px).\n\nEden label (269.6,196.1) rotate -63: river Penrith (x(-2.75,54.66)=276,y=214.6) → Carlisle (260.8,184.7): at y 196, x≈265.5. Label center (269.6,196) — 4px east... perpendicular offset ok. Carlisle label (260.8,176.7) spans ~235-287 — Eden label top? rotated -63 at center (269.6,196): extends ±22 along -63°: endpoints (259.6,215.6) and (279.6,176.5)!! top end (279.6,176.5) near Carlisle label (235-287 at 176.7)!! Collision. Move Eden label south: p [-2.78,54.72] → x=273.6,y=206.8: endpoints (263.6,226.4)-(283.6,187.2). Carlisle label bottom ~179. OK gap 8px. Fine.\n\nLune label (292,267.2) rotate 65: river Kirkby Lonsdale (288,275.1) → source (-2.6,54.45) x=288,y=242.7?? wait Lune source (-2.6,54.45): x=288,y=(56.3-54.45)131=242.35. River vertical x~288 from 242 to 275, then Hornby (284.8,286.6), Lancaster (272,294.9). Label center (292,267) — 4px east of river. rotate 65 (river flows S). OK. Ribble label (307.2,298.2) rotate 72: river Settle (313.6,291.7) → (-2.35,53.95) x=308,y=303.9. Label (307,298) — on river; offset west: p [-2.42,54.0] → x=302.4,y=302.6. River at y 302: x≈308.5. Label 6px west. rotate 72. Lune label bottom? vertical-ish label at (292,267) endpoints ±18: (284,283)-(300,251). Ribble label top (302,302)-(312,284)?? endpoints of Ribble label rotate 72 ±16: (297,317)-(307,287). Lune bottom (284,283) vs Ribble top (307,287) — clear.\n\nSwale label — check collision with Wensleydale... fine.\n\nOuse label (402.4,324.5) rotate 82: river York (409.6,305.6) → Selby (x(-1.07,53.78)=410.4,y=329.1). At y 324, river x≈410.2. Label 8px west. OK. Wharfe joins at (x(-1.13,53.83)=405.6,y=321.7)! Wharfe mouth near label. Wharfe label at (374.4,308.7) rotate 8 — clear (28px west).\n\nAire label (349.6,315.9) rotate 13: river Keighley (x(-1.91,53.87)=343.2,y=318.3) → Leeds (372,327.5): at y 316, x≈342. Label center (349.6,316) — hmm on river slightly north. rotate 13 OK. Leeds label (379,331) — clear. Castleford... Aire & Calder... fine.\n\nStour label (329.6,707.1) rotate 18: river Blandford (323.2,713.7) → Wimborne (x(-1.99,50.8)=336.8,y=720.5). Label center (329.6,707) — 8px above. OK. Hants Avon? no label (decided skip? I said maybe \"R. Avon\" — skip, avoid confusion).\n\nTest/Itchen no labels.\n\nDorset Stour vs Avon Hants confluence at Christchurch — fine.\n\nMedway mouth/Thames estuary: fine.\n\nNow — one more check on the Welsh border label \"WALES\" (212,491.8): Teme river at Ludlow (x(-2.72,52.37)=278.4,y=519.7) — clear. Severn label (312,500) — clear.\n\n\"SCOTLAND\" (280,112.6): N Tyne branch at (-2.35,55.1) x=308,y=156.8 → (-2.2,55.05) x=320,y=163.4 — clear.\n\nIrish Sea label (180,328): Ribble mouth (262.4,335.7) — clear. \n\nCompass (648,115): graticule lines pass; fine.\n\nLegend contents and scale bar: 100 km at lat ~52.5 = 80px/(111.32cos(52.5°))km... cos52.5=0.6088 → 67.76 km/deg → 80px/67.76km = 1.18 px/km → 100km = 118px. Scale bar: x 615-733?? legend width... legend rect (500,788,w=210,h=94). Inside: \n- \"LEGEND\" header at (520,806) size 10 ls 3 fill #555.\n- River: casing+core line (518,822)-(552,822); text (560,825) \"River\" size 10.5.\n- Canal: dashed (518,838)-(552,838); text \"Canal\".\n- Border: dashed gray (518,854)-(552,854); text \"Border\".\n- City: dot at (526,870) r2.6; text (560,873) \"City\".\nRight column x 615-700:\n- Scale bar: from (612,846) to (612+118=730)? exceeds 710 rect edge (rect ends 710). Make bar 0-80 km = 94px: (612,848)-(706,848) ticks at 0,47(40km),94(80km) labels \"0\",\"40\",\"80 km\" tiny at y 838/862. Hmm cramped. Alternative: legend rect wider: (495,788) w 220 → ends 715. Bar (610,850)-(704,850) = 94px = 80km; labels 0/40/80. Or place scale bar below legend separately at (520,900)? viewBox ends 895. Let me: legend rect (495,786,220,96) → bottom 882; viewBox y to 890. Scale bar row at bottom of legend spanning full width: bar from (515,868) to (633,868) (118px=100km), ticks 0/50/100 at 515/574/633, labels above bar y 860 tiny, \"km\" after 100. Legend items rows y 822,838,854 in col1; col2 (x 630+): City dot (640,822), text; and maybe \"Estuary\" sample? skip. Col2: dot City (822), and... canal/border in col1. Actually arrange:\n row1: River (col1), City (col2)\n row2: Canal (col1), Border (col2)\n row3: scale bar spanning bottom.\nPositions: col1 x samples 512-548, text 556; col2 samples 640-676, text 684. Rows y 820, 838. Scale bar y 866, labels y 858. Rect (495,786,225,98) → bottom 884. Hmm viewBox 890 tall → set \"-25 20 740 875\" → y 20..895. OK.\n\nCompass rose design:\n\n circle r=17 fill #ffffffcc stroke #5d8fb3\n polygon N arrow: points \"0,-14 4,0 0,-4 -4,0\" fill #2c4a63? plus S small arrow; \"N\" text at (0,-22) size 11 fill #2c4a63 middle.\nAdd E/W ticks small.\n\nAlso add subtle sea motif? skip.\n\nGraticule: for lon -6..1 step 1: x from 16 to 576... lon -6 → x=16; lon 1 → x=576; lon 1.75 max. Lines from y top (lat 56 → y=39.3) to bottom (lat 50 → y=825.4). For lat 50..56: y from 825.4 to 39.3. Stroke #ffffff? On sea use rgba(255,255,255,.35); over land they'd clash — draw graticule UNDER land? Then visible only on sea — classic. Yes: draw graticule after sea, before land. \n\nLand fill: to add depth, fill #f3ecd9; then a second path stroke slightly darker. Also maybe drop shadow under land: filter or offset path fill rgba(0,0,0,0.08) translated (2,3)? Nice: draw coast path fill shadow first.\n\nRivers clipped to land? Rivers end at coast; with smoothing they might overshoot slightly into sea — acceptable; or set clipPath to land+sea everything (no clip needed).\n\nAlso canal endpoints at London/Birmingham etc fine.\n\nFonts via Google: . SVG text font-family \"EB Garamond\", Georgia, serif.\n\nJS structure:\nconst svg = document.getElementById('map');\nconst NS = 'http://www.w3.org/2000/svg';\nfunction el(name, attrs, parent){...}\nconst X = lon => (lon+6.2)80; const Y = lat => (56.3-lat)131;\nfunction pts(arr){return arr.map(([a,b])=>[X(a),Y(b)]);}\nfunction smooth(points, closed){ // catmull-rom\n const p = points;\n let d = `M ${p[0][0].toFixed(1)} ${p[0][1].toFixed(1)}`;\n const get = i => closed ? p[(i+p.length)%p.length] : p[Math.min(Math.max(i,0),p.length-1)];\n for(let i=0;i with transform=`translate(x,y) rotate(r)`, text-anchor middle (for rotated river labels), class.\n\nSea labels: text-anchor middle, letter-spacing via attribute (SVG supports letter-spacing).\n\nLet me also add small \"estuary\" labels? skip.\n\nOne more feature: major rivers get slightly bolder. Already handled by width classes.\n\nDouble-check canal routes don't look like rivers crossing weirdly:\n- Grand Union from London (485.6,628.8) → Uxbridge (x(-0.48,51.55)=457.6,y=622.6) → Watford?? (-0.4,51.66) x=464,y=608.2 → hmm Uxbridge to Watford goes N... fine → Tring (x(-0.66,51.79)=443.2,y=596.5) → Leighton (x(-0.66,51.92)=443.2,y=579.5)?? both -0.66 → vertical; fine → MK (x(-0.76,52.04)=435.2,y=563.8) → Weedon (x(-1.08,52.23)=409.6,y=538.9) → Braunston (x(-1.2,52.29)=400,y=531) → Warwick (x(-1.58,52.28)=369.6,y=532.3)?? Braunston→Warwick goes west... then Birmingham (344,500.4). OK dashed canal crosses Great Ouse label area (454,537)? Canal at MK (435,564)→Weedon (410,539): label at (454,537) clear.\n- Oxford canal: Oxford (395.2,596) → Banbury (x(-1.34,52.06)=388.8,y=557.7) → Coventry (x(-1.51,52.41)=375.2,y=515.4). Crosses GU near Braunston — canals intersect: realistic!\n- Trent & Mersey: Derwent Mouth (x(-1.28,52.86)=393.6,y=451.6) → Burton (365.6,458.7)?? x(-1.63,52.8)=365.6,y=458.7 → Stone (x(-2.15,52.9)=324,y=444.9) → Stoke (321.6,430.6) → Kidsgrove (x(-2.24,53.08)=316.8,y=416.3) → Middlewich (x(-2.44,53.19)=300.8,y=406.3) → Northwich (x(-2.52,53.26)=294.4,y=397.1) → Preston Brook (x(-2.65,53.34)=284,y=386.3)?? ends near Mersey label (292,390)!! Canal dashed passes under label. Acceptable — or end canal at Northwich. Keep; dashes under label minor.\n Hmm Mersey label at (292,390) — canal endpoint (284,386) 8px away. OK.\n- Leeds & Liverpool: Leeds (372,327.5) → Skipton (333.6,313.7)?? x(-2.03,53.96)=333.6,y=313.7 → Burnley (x(-2.24,53.79)=316.8,y=329.8) → Blackburn (x(-2.48,53.75)=297.6,y=335) → Wigan (x(-2.63,53.55)=285.6,y=360.3) → Liverpool (258.4,377.4). Passes near Ribble label (302,302)? clear. Near Mersey label (292,390)? endpoint (258,377) clear.\n Wait Skipton x: (-2.03+6.2)80=333.6 yes. Aire river also Leeds→Skipton (343,318)→(333.6,291.7 Settle)... canal and river close between Leeds-Skipton: realistic (canal follows Aire valley). Good.\n- Kennet & Avon: Reading (417.6,635.4) → Newbury (390.4,645.2) → Hungerford (x(-1.52,51.41)=374.4,y=643.8) → Devizes (336,645.9) → Bradford? → Bath (307.2,648.6). Follows Kennet then Avon. Thames label (436,615) clear.\n\nOK. Also add tiny canal \"Gloucester & Sharpness\"? skip.\n\nAlso maybe add \"Bridgewater Canal\" Manchester? skip.\n\nNow build the HTML with nice styling:\n\n- body bg: #e8edf1? Use a soft paper: #f2f0ea with subtle. Map card: white padding, rounded, shadow, max-width 760px margin auto.\n- h1: EB Garamond 600, #23415c, letter-spacing 1px, size 34.\n- sub: italic #5d7a90.\n- divider: small dashed rule with diamond.\n- footer: tiny #8a97a3.\n\nResponsive: svg width 100% height auto.\n\nWrite the script carefully. Also text rendering in SVG uses same font.\n\nPotential label overlaps I should double-check once more in dense areas:\n\nHumber area: York label (416.6,309.6) start spans 416-445; Ouse label vertical at x~402 y 300-350; Hull label (476.6,339) start; Humber label center (446,329.5) spans 420-472 rotate -2; York label ends 445 at y 309 — Humber at 329 — OK. Ouse label top end? rotate 82 center (402.4,324.5) length ~36: endpoints (400,306)-(405,343). York label at (416.6,309.6) — clear. Selby/Goole rivers fine.\n\nEast Midlands: Trent label vertical x 441.6 y 380-427; Witham label (478.4,413.3) rotate 33 spans ~455-500 diagonal; Lincoln dot? not included. OK. Nene label (448,508) — near Welland river (Stamford 457.6,479.5 → Spalding (x(-0.18,52.79)=481.6,y=458)? clear.\n\nEast Anglia: Great Ouse label (454.4,536.9) rotate -28 spans ~425-485 diagonal; Cambridge label (512.6,541) start spans 512-565 — clear. Bedford? none.\n\nLondon area: London label (493,621) start; Thames label (394-478,615); Medway label (528,648.5) rotate -18 spans ~500-556 diagonal — London label ends ~545 at y 621; Medway top ~640 — clear.\n\nThames estuary coast: Gravesend (x(0.37,51.44)=525.6,y=637.9)?? recompute: (0.37+6.2)80=525.6, y=(56.3-51.44)131=636.7. Medway label (528,648) — 11px below coast point... coast at Sheerness (x(0.76,51.44)=556.8,y=636.7): the south bank coast y~636-640 at x 525-556. Medway label baseline 648.5 top ~638 — touches coast line?! The coast here is the Thames south bank going W-E at y~637. Medway label at y 648 is just south (land side, Kent). OK — label on land below coast. But Medway river flows to Sheerness through Rochester (x(0.5,51.39)=536,y=643.5) — river at y 643; label at 648 ON river?? Label center (528,648.5): river Rochester (536,643.5) → (x(0.58,51.41)=542.4,y=640.9): at x 528, river is NW: Maidstone (537.6,658.9)→Rochester (536,643.5): at x 528?? River is at x 536-538 there. Label center x 528 — 8px west. Baseline 648 top 638. River segment Tonbridge→Maidstone at y 659-667. OK label sits between the two reaches — acceptable, rotate -18.\n\nActually move Medway label slightly: p [0.36,51.33] → x=524.8,y=651.1 rotate -18. Fine.\n\nSouthern: Test/Itchen/Southampton: Southampton label (386.4,699.4) spans ~345-428; Itchen river from Winchester (x(-1.31,51.06)=391.2,y=681.5) south to (386.4,707.4). Label at 699 crosses Itchen?? Itchen at y 699: x≈388. Label spans 345-428 — crosses river line. Labels crossing thin rivers is common on maps (white halo helps). I'll add paint-order stroke halo on labels: stroke #f4ecd9 (land color) stroke-width 2.5, paint-order stroke. That solves readability everywhere. \n\nSimilarly city labels get halo. River labels halo too (halo sea/land? use #f4ecd9; over sea it'll show slightly — acceptable, or use white-ish #fbf7ec). Use rgba(251,247,236,0.85)? paint-order stroke with stroke-opacity .8.\n\nOK halo for all labels.\n\nCity dots get white ring: stroke #fbf7ec 1.2.\n\nNow, one more: \"Isle of Wight\" label at (392,772)?? IoW polygon: points lon -1.57..-1.08 → x 370.4..409.6; lat 50.58..50.73 → y 749.4? compute: 56.3-50.73=5.57131=729.7 (Ryde); 56.3-50.58=5.72131=749.3 (St Catherine's). So IoW y range 729.7-749.3. Label below at (390,764) size 9.5 italic spans ~352-428. English Channel label top ~ y 781 at x 278-474. Gap 7px. Move IoW label to (390,762), channel label y to 796 (p lat 50.2 → y=799). Set channel p [-1.5,50.18] → y=801.4, spans y ~790-802. IoW label bottom ~767. OK.\n\nSouthampton Water coast notch at (391.2,713.9)/(x(-1.33,50.79)=389.6,y=721.4) — IoW label at 762 clear.\n\nAlso Portsmouth not labeled — fine.\n\nRight, also consider adding \"Spithead\"/\"Solent\"? no.\n\nLet me also double check Exe label vs Exeter label: Exeter label end anchor (206.6,726) — \"Exeter\" ~38px → spans 168-207. Exe label vertical at x~221 y 703-740. Clear.\n\nPlymouth label below dot (164.8,790.6) spans ~130-200 — over sea. Coast at y 790? lat=56.3-790.6/131=50.26 → coast near Plymouth y~776-782; below is sound/sea. OK. Tamar label (148.8,751) rotate 66 — clear (40px above).\n\nDart label (200,762) rotate 45 size 10 spans diagonal ~ (193,755)-(207,769). Plymouth label top ~783. OK.\n\nNow Irish Sea / Wales labels clear.\n\nAlright — also small touch: add \"Lizard Point\" or \"Land's End\"? skip.\n\nLet me also include a couple more rivers for completeness in the far SW: River Fal? skip. River Fowey? skip. River Taw (Barnstaple)? North Devon looks empty: add Taw & Torridge briefly:\nTAW: source Dartmoor (-3.9,50.65)? → Taw: [-3.92,50.7],[-3.85,50.85],[-3.95,50.95],[-4.05,51.05],[-4.08,51.08] Barnstaple → mouth [-4.15,51.08]?? Taw-Torridge estuary at Instow (-4.18,51.05). Points: [-3.9,50.68],[-3.83,50.8],[-3.9,50.92],[-4.0,51.0],[-4.06,51.08],[-4.15,51.06].\nTORRIDGE: [-4.2,50.85]?? source near Hartland (-4.35,50.95)?,[-4.25,50.9],[-4.2,50.95],[-4.14,51.0],[-4.15,51.06] join estuary. Points: [-4.3,50.92],[-4.22,50.95],[-4.18,51.0],[-4.15,51.06].\nAdd both small (w 1.6), label \"Taw\" tiny at (-3.95,50.9) → x=180,y=707.1 rotate -60? Taw flows N: rotate -80 at p [-3.92,50.92] → x=182.4,y=704.5. OK tiny. Skip Torridge label.\n\nAlso River Parrett (Somerset): Bridgwater (-3.0,51.13)? Parrett from (-2.85,50.95)? → Bridgwater → mouth (-3.0,51.22). Points: [-2.9,50.92],[-2.95,51.0],[-2.98,51.1],[-3.0,51.13],[-3.03,51.22] mouth. Label? tiny \"Parrett\" at (-2.9,51.0) → x=264,y=694.2 rotate -70 size 9.5? Include line, skip label? Include label small — Somerset looks empty otherwise. Add.\nAlso River Tone? skip. River Brue? skip.\n\nEast: River Colne (Essex)? skip. River Orwell? skip — but Felixstowe/Harwich area fine without. River Deben? skip. River Blyth? skip. River Waveney? skip. River Yare (Norwich)! Norwich sits on Yare: Yare from (-1.0? source near Shipdham (0.9,52.6)?) → Norwich (1.3,52.63) → Yarmouth (1.73,52.6). Points: [0.85,52.58],[1.05,52.6],[1.2,52.62],[1.3,52.63],[1.45,52.62],[1.6,52.6],[1.73,52.6] mouth. Label tiny \"Yare\" at (1.45,52.66) → x=612,y=457.9? lat 52.66 → y=476.9. p [1.45,52.66] x=612,y=476.9 rotate 2 size 9.5. Norwich label end (593,475.8)!! Collision — Yare label at 612 start ~605? center 612 spans ~600-624. Norwich label ends 593. OK 7px gap. Coast Yarmouth (634.4,484.7). Yare label at (612,477) — clear of coast. Add river w 1.6.\nAlso River Wensum joins at Norwich — skip.\nRiver Bure? skip.\n\nKent: River Stour (Kent) Canterbury → Sandwich: points [1.08,51.28],[1.15,51.28],[1.25,51.25],[1.35,51.23],[1.42,51.27]? mouth near (1.4,51.25)?? Stour flows to Pegwell Bay near Ramsgate. Points: [0.95,51.23]? source near Ashford (0.87,51.15)? → Canterbury (1.08,51.28) → (1.2,51.28) → (1.35,51.24) → mouth (1.4,51.29)?

Avon label (312-352 at baseline 629.6?? recompute: p[-2.05,51.52] y=(56.3-51.52)131=626.1. spans y ~616-626. Clear of Bristol top 631. \n- Wye (288,563.4) r60 spans ~(278,543)-(298,583): Gloucester label (323.8,585.6 start spans 323-380): clear. Teme no label. Monmouth... fine.\n- Severn (312,500.4) r62 spans ~(293,535)-(331,466): Welsh border x at y 500: border lon at lat ~52.45: (-3.08,52.5) x=249.6 — clear. Birmingham label (337,504 end spans ~277-337)!! Severn label at (293-331, 466-535) overlaps Birmingham label region (277-337 at y ~497-507)!! The Severn label line passes (312,500) — directly through Birmingham label text zone!! Collision. Fix: move Birmingham label above dot: anchor middle (344,492.4) dy -8 → spans ~304-384 at y 492. Severn label top right end (331,466)... at y 492, Severn label x ≈ 306-318 (center 312 at 500, slope) — overlap x 304-318 possible!! Ugh. Move Severn label south along river: p [-2.28,52.34] → x=313.6,y=518.1?? that's near Stour... skip Stour so OK: label center (313.6,518.1) r62 spans ~(294,553)-(333,483). Birmingham label (304-384 at 485-500): overlap zone x 304-333 y 483-500 — Severn label passes through (320,500)-(333,483)!! STILL overlapping. \n Alternative: put Severn label on the WEST side of river: p [-2.4,52.4] → x=304,y=509.7 spans (285,544)-(323,475): Birmingham label spans 304-384 at y 485-500 → overlap at x 304-323, y 485-509!! STILL.\n Rethink: Birmingham dot (344,500.4). Label options: below dot (344,512.4 middle spans 304-384 at y ~505-515): Severn label at p[-2.3,52.48] (312,500.4) spans (293,535)-(331,466) — passes (312,500) region → overlap again!!\n Move Severn label NORTH along river near Ironbridge: p [-2.42,52.62] → x=302.4,y=479.9 r62 spans ~(283,514)-(321,445). Birmingham label below dot (304-384, 505-515): overlap x 304-321 at y 505-514!! Marginal corner touch (Severn label bottom-right corner (321,514) vs Birmingham label left end (304,505-515)) — corner overlap likely touches.\n Hmm. Choose Birmingham label RIGHT of dot: anchor start (351,504) spans 351-431 at y ~497-507. What's there? Coventry canal (Coventry (375.2,515.4))... Oxford canal endpoint Coventry (375.2,515.4) 11px below label — OK. GU canal passes (-1.8,52.45) x=352,y=510 → (-1.9,52.48) endpoint 344: label at y 497-507 vs canal points y 510 — grazes. Halo handles. And Severn label at (283-321, 445-514): clear of 351+. OK!\n FINAL: Birmingham label anchor start dx 7 dy 4 → (351,504.4). Severn label p [-2.42,52.62] → (302.4,479.9) r62. Check Severn label vs Ironbridge river point (297.6,480.8): label center (302,480) — 5px east of river. Good. And vs Trent&Mercy canal? canal at Stone (324,444.9) — clear. Derby Derwent (x(-1.6,53.13)=368,y=412.9...) clear.\n- Great Ouse label (454.4,536.9) r-28 spans ~(429,550)-(480,524): GU canal at MK (435.2,563.8)→(-0.85,52.1) x=428,y=551.3: canal passes (428,551) near label start (429,550)!! grazes. Halo OK.\n- Cam... fine.\n\nAlso London halo over river fine.\n\nCity dots: also add small dot for \"Reading\"? no.\n\nOne more: Sheffield label below (378.4,394.5) middle spans ~355-402 at y ~388-398: Don river at Sheffield (378.4,382.5) → Rotherham (x(-1.36,53.43)=387.2,y=376) — label below dot, river goes NE — OK. Trent label vertical x 441.6 — clear.\n\nNottingham label (404,431) spans 375-433: Trent river at Nottingham (404,439)?? point (-1.15,52.95) x=404,y=439.5 — label 8px above river. Soar joins at (393.6,451.6) clear. OK.\n\nNow — compass: translate(648,115). Check North Sea label (616,222.9 spans ~540-690): compass at 115 — clear.\n\nGraticule extent: lon lines -6,-5,...1 → x 16,96,176,256,336,416,496,576. lat lines 50..56 → y 825.4,694.2,563,431.8,300.6,169.4,38.2? compute: lat 56 → (0.3)*131=39.3; 55 → 170.3; 54 → 301.3; 53 → 432.3; 52 → 563.3; 51 → 694.3; 50 → 825.3. Draw from x 16..640? Just draw each line across full viewBox; they're under land, visible on sea. Also add subtle border rect.\n\nFrame: rect (-15,30) to (720,890)? viewBox \"-25 20 745 880\" → covers x -25..720, y 20..900. Frame rect: x -12, y 32, w 720, h 856 → to (708,888). Inset 4px second rect. Stroke #7f8fa0 / thinner.\n\nHmm Lowestoft x 636; North Sea label to 690; frame at 708 OK. Compass at 648±25 → 673 OK.\n\nTitle area: HTML handles it; SVG top y 20: coast min y 69 (Berwick); SCOTLAND 112; Tweed 91. Graticule top 39. Frame top 32. Good.\n\nLegend rect: (495,786) w 222 h 98 → (717,884) — frame inner edge 708!! Legend overlaps frame. Move legend: (480,784) w 220 h 96 → (700,880). Frame at 708 — OK 8px gap. But \"ENGLISH CHANNEL\" label spans 278-474 at y ~790-802: legend left edge 480 — 6px gap. OK.\n\nLegend internals (origin 480,784):\n- bg rect fill #fbf8f1 stroke #9aa7b2, opacity .95, rx 6.\n- \"LEGEND\" at (592,801) middle ls 3 size 10 fill #4a5a68.\n- Row1 y 820: river sample x 495-530: casing line w 5 #c9e0ef + core w 2.6 #3e7cb1; text \"River\" at 538 baseline 823 size 11 fill #333.\n- Row2 y 839: canal sample dashed #8aa5b5 w 1.8 dash 5 3; text \"Canal\".\n- Row3 y 858: border sample dashed #a39d8c w 1.5 dash 6 4; text \"Country border\".\n- Col2 x 600: city dot at (606,820) r 3 fill #2b2b2b stroke #fbf7ec; text \"City\" at 614 baseline 823. \n- Scale bar: y 858 col2: line (600,858)-(694,858) = 94px ≈ 80 km; ticks at 0, 47 (40), 94 (80): small vertical ticks h 4; labels \"0\" (600,850 middle), \"40\" (647,850), \"80 km\" (694+? put \"80\" middle 694 and \"km\" after?) simpler: labels below? Row3 col1 is border... Scale labels at y 872: \"0\" (600), \"40\" (647), \"80 km\" (700 end-anchor). Legend height 96 → bottom 880: ok y 872 inside.\nHmm col1 rows at 820/839/858 and scale bar at 858 same row — col2 only, fine.\n\nWait col1 row3 text \"Country border\" at 538 spans 538-610 — crosses col2 (600)! Shorten text \"Border\". OK: \"Border\".\n\nScale: 94px = 80 km (at lat 53: 1.18 px/km → 80km=94.4px). \n\nCompass rose details:\n\n \n \n \n N\n ticks E/W: line (11,0)-(14,0) etc? add small: . \n\nFine.\n\nSea gradient: linearGradient id=\"sea\" x1 0 y1 0 x2 0 y2 1: stops #d6e7f0, #c2dcea. Also subtle second radial highlight? skip.\n\nLand shadow: use coastline path with fill #000 opacity 0.06, transform translate(3,4). Then land fill.\n\nAlso add slight coastline stroke: #8b9681 w 1.2.\n\nBorders: draw dashed lines ON TOP of land (after land fill): SCOT_BORDER & WALES_BORDER smooth paths.\n\nRivers group after borders. Canals after rivers? Canals dashed thin — draw before rivers? Order: canals under rivers fine either way. I'll draw canals after rivers so dashes visible, but at junctions rivers cross... fine.\n\nLabels last. Halo via CSS: .lbl { paint-order: stroke; stroke: rgba(250,246,235,.9); stroke-width: 2.6px; stroke-linejoin: round; }\n\nCity dots: fill #2b2b2b.\n\nAlso add small river-mouth widening? skip — estuaries handled by coastline.\n\nLet me also double-check the coastline smoothing won't create weird self-intersections at estuary necks (Thames: Gravesend (0.37,51.44) → (0.36,51.47) → (0.5,51.5): tight turn; Catmull-Rom handles fine.\n\nHumber: Trent Falls (-0.69,53.7) → (-0.6,53.72): sharp U-turn; smoothing rounds it — OK.\n\nDee: (-3.13,53.31) → (-3.02,53.24) → (-2.9,53.19) then border (-2.95,53.1): turn OK.\n\nOne concern: the closed Catmull-Rom across the whole coast with ~180 points — fine.\n\nAlso Wash: (0.45,52.85) → (0.39,52.75): fine.\n\nNow check viewBox bottom: Lizard y 830.5; legend 880; frame 888. viewBox \"-25 20 745 878\" → y 20..898. Height 878, width 745 → aspect 0.848. Card max-width 720px → map ~ 850px tall on desktop. OK.\n\nActually let me reconsider: is 745 wide enough? Frame right 708 + margin 12 = 720 → viewBox right 720 ✓. Left: frame -12, margin → -25 ✓ (Land's End 38). Top: frame 32, margin → 20 ✓. Bottom: frame 888 + 10 → 898 ✓.\n\nWrite CSS:\nbody { margin:0; background:#e9edf1; font-family:'EB Garamond',Georgia,serif; color:#333; }\n.wrap { max-width:780px; margin:0 auto; padding:28px 16px 40px; }\nheader { text-align:center; margin-bottom:18px; }\nh1 { font-size:34px; font-weight:600; color:#23405c; letter-spacing:.5px; margin:0 0 6px; }\n.sub { font-style:italic; color:#5d7a90; font-size:17px; margin:0; }\n.rule { width:220px; margin:14px auto 0; border-top:1px solid #b7c4ce; position:relative; }\n.rule::after { content:'◆'; position:absolute; top:-8px; left:50%; transform:translateX(-50%); color:#7fa0b8; font-size:10px; background:#e9edf1; padding:0 8px; }\n.map-card { background:#fdfcf8; border:1px solid #d5dde3; border-radius:10px; box-shadow:0 10px 30px rgba(35,64,92,.12); padding:14px; }\nsvg { display:block; width:100%; height:auto; }\nfooter { text-align:center; color:#8a97a3; font-size:12.5px; margin-top:14px; font-style:italic; }\n\nSVG text classes:\n.sea-lbl { fill:#5d8fb3; font-weight:500; }\n.river-lbl { fill:#2e6da4; font-style:italic; }\n.city-lbl { fill:#333; }\n.country-lbl { fill:#96917f; }\n.lbl { paint-order:stroke; stroke:rgba(251,247,236,.88); stroke-width:2.8; stroke-linejoin:round; }\n\nJS: build everything. Also numbers rounding.\n\nFor halo on sea labels maybe stroke sea color? .lbl uses cream halo; over sea cream halo slightly visible but fine (like label knockouts on real maps).\n\nLet me write smoothClosed:\nfunction closedPath(p){\n const n=p.length; const g=i=>p[(i%n+n)%n];\n let d=`M${f(p[0][0])} ${f(p[0][1])}`;\n for(let i=0;iv.toFixed(1).\n\nRivers: for each: el path d=openPath(pts) class river with stroke-width.\n\nDraw casing: one all paths stroke #c9e0ef w+1.8; then core group stroke #3e7cb1 w.\n\nCanals: stroke #7d99ab w 1.5 dash \"5 3.2\" opacity .95, plus no casing (or light casing 0.5?). Keep simple.\n\nLabels: text elements with x/y or transform rotate.\n\nFor rotated labels: transform=`translate(${x} ${y}) rotate(${r})`, text-anchor middle, dominant-baseline central? Use dy .35em? I'll set attribute dy=\"0.35em\" for vertical centering-ish. For rotated river labels, baseline central is better: dominant-baseline=\"middle\". Hmm cross-browser: use dy=\"0.32em\".\n\nCities: dot circle + text with dx/dy and anchor.\n\nAlso add tiny \"estuary\" blue for Thames mouth? Not needed.\n\nFinally, ensure the whole thing works without external JS libs — only Google Fonts link (allowed, include full link tag). If fonts blocked, Georgia serif fallback.\n\nOne more check — \"IRISH SEA\" spans 108-252 at y 328: coast Southport (255.2,347.8), Formby (250.4,360.5): label end 252 at y 328 vs coast y 348+ — clear. Morecambe Bay label none. Fleetwood coast (x(-3.0,53.93)=256,y=310.5)!! At y 310, coast x 256 — label at y 328 spans to 252: the coast segment Fleetwood (256,310)→Blackpool (252,369.4): at y 328, coast x ≈ 255. Label end 252 < 255 — clear by 3px. Halo 2.8 — ok.\n\n\"BRISTOL CHANNEL\" (180,640.4) spans ~102-258: Severn mouth river end (268,646.9) — clear. Coast Minehead (218.4,666.8)?? at y 666 — label baseline 640, bottom ~644 — clear. Wales not drawn — good. Ilfracombe (166.4,667) clear.\n\n\"WALES\" (212,491.8) spans ~182-242: border x at lat 52.55 ≈ 249 — clear. Teme river at (-2.72,52.37) x=278.4 — clear.\n\n\"SCOTLAND\" (280,112.6) spans ~238-322: border at lat 55.44 → x: between (-2.5,55.42) x=296,y=115.5 and (-2.62,55.28) x=286.4,y=131.2 — border at y 112 near x 296. Label spans to 322 — crosses border?? Label y 112.6 baseline, top ~101, bottom ~116. Border at y 112: x≈297. Label text up to 322 → crosses border line into England side. Move label west/north: p [-2.95,55.5] → x=260,y=104.5 spans ~218-302... still crosses 297? At y 104.5, border x: between (-2.35,55.55) x=308,y=98.4 and (-2.5,55.42) x=296,y=115.5: at y 104.5 border x≈304. Label end 302 < 304 ✓ barely. Or center (255,100): spans 213-297. p [-3.0,55.54] → x=256,y=99.6. Border at y 99.6 x≈307.5 ✓ clear. SCOTLAND at (256,99.6) r 0. Tweed label (310.4,91.7) spans 288-332 r-18 at y ~85-99: SCOTLAND end 297 vs Tweed start 288 at similar y!! Overlap x 288-297, y: SCOTLAND baseline 99.6 top 88; Tweed label center (310.4,91.7) rotated -18 spans (289,99)-(332,84) approx — yes overlap zone (289-297, 88-99). Move Tweed label downstream-east: p [-2.18,55.66] → x=321.6,y=83.7 spans ~(300,91)-(343,76) r-18. SCOTLAND (213-297) clear ✓. Coast Berwick (336,69.4) — Tweed label end (343,76): near coast point? Coast from (-1.9,55.72) x=344,y=75.6 → Berwick (336,69.4): Tweed label end (343,76) — ON coast!! Tweed mouth at Berwick (336,69.4). Move label: p [-2.24,55.63] → x=316.8,y=87.5 r-15 spans ~(295,94)-(339,81): coast at y 87: segment (-2.1,55.7) x=328,y=78 → (-2.25,55.65) x=316,y=85.6 → hmm Tweed RIVER points: (-2.1,55.7) (328,78.3), (-2.25,55.65) (316,85.6), (-2.4,55.6) (304,92.1). The label center (316.8,87.5) sits right along the river (which is the point — river label). Border SCOTLAND line passes through? The border follows Tweed from ~(-2.62,55.28)? No — border leaves Tweed at (-2.55,55.42)?? Actually border: Cheviots then joins Tweed near (-2.9,55.55)?? My border points: [-2.95,55.05]... wait border ends at Gretna west; the EAST part: from Berwick the border goes SW along Tweed then south into Cheviots: points [-2.00,55.77],[-2.18,55.68],[-2.35,55.55],[-2.50,55.42]... So the border line overlaps the Tweed river region but my Tweed river points ([-2.55,55.58]→Berwick) and border points differ slightly — they'll render as two close lines. Real geography: Tweed's lower reach is fully in England (border leaves it near Carham). Fine—two lines acceptable.\n Tweed label at (316.8,87.5) r-15 spans ~(295,94)-(339,81): border point (-2.35,55.55) x=308,y=98.4 — near label bottom-left (295,94)? 6px — halo ok. Meh, acceptable.\n\nAlso SCOTLAND label (256,99.6): N Tyne at (-2.35,55.1) x=308,y=156.8 — far. OK.\n\nCheck Tyne branches vs SCOTLAND: fine.\n\nAlso \"Coquet\" river no label ✓.\n\nAlright — also the map needs attribution-ish footer: \"Schematic map · river courses stylised · not for navigation\".\n\nLet me also add a subtle decorative \"sea monster\"/ship? A tiny ship silhouette in the Channel could be charming: skip, keep clean. Maybe a small ornamental compass is enough.\n\nNow write the code. I'll be careful with the label halo: define CSS in

England's waterways
