CHLOE SKINNER COVERAGE MAP - SOURCE AND IMPLEMENTATION NOTES
Prepared 8 November 2026

FILE
coverage-map.svg. Standalone SVG, 550 x 440 viewBox. No scripts or external assets.

SCOPE
The business plan says local in-person support primarily in South Oxfordshire and South Buckinghamshire, remote support throughout the UK, and other assignments by arrangement. The map illustrates those broad regions; named towns are orientation points only. Do not use the map to imply a fixed radius, acceptance of a particular assignment, or a postal-address location.

GEOMETRY
Real ONS South Oxfordshire local-authority boundary and the southern portion of the real Buckinghamshire unitary-authority boundary. The Buckinghamshire polygon continues north beyond the viewport. No South Bucks former district boundary is used. There are no invented roads, rivers, or coverage-radius outlines. Polygon geometry is generalised further to 0.001 degree by the ONS query and rendered with a north-up local equirectangular projection; longitude is scaled by cos(51.64 degrees).

PLACEMENT AND MOBILE USE
The dot centres are projected directly from those coordinates; label positions have been adjusted for legibility. Towns are not a travel-time promise. The SVG includes a title/description and responsive label sizes. Because footer attribution in a scaled image becomes small, put the full attribution above in a readable page footnote or credits panel and add a real HTML figcaption: "Area illustration. Locations and availability agreed individually." A suitable alt is "Map illustrating South Oxfordshire and South Buckinghamshire, with local towns shown for orientation."

VALIDATION
XML parsed. Two geographic polygons retained and five coordinate-derived town markers present. Rendered with Inkscape and visually inspected at 550 and 360 pixels wide. Labels are legible and no labels collide or clip. All geometry and town locations were retrieved from the cited source pages on 8 November 2026.
