Map of the United Kingdom by parliamentary constituency, one number per seat, with the nation borders

About this template

Data: one row per Westminster constituency (the 650 seats on the July 2024 boundaries) with its ONS code (E14001063 for Aldershot) or its name, and a number. A seat with no row stays grey. The nation borders are drawn on top; Orkney and Shetland are drawn east of the mainland, at their own scale. Same design as the nation, region and local authority maps.

A choropleth map of the regions of the "uk-constituencies" geography, each region filled by one number from your data (the "margin" column). The borders of the "uk-nations" regions are drawn on top of the regions in dark navy blue, 0.5 units wide, so the finer regions read inside their larger units.

A sequential colour scale from pale blue for the smallest values to deep navy blue for the largest; pinned to 0 to 50, so values beyond the ends take the end colour and the colour bar says ≤ and ≥; a gradient colour bar below the map, with its labels underneath; values formatted 0 decimals, a "pts" suffix; on a white canvas (#ffffff) with near-black text — a light theme; 0.25-unit hairline outlines between regions.

The title and description are left-aligned above the chart. Font: Inter (the default); a source line with a link sits at the bottom, with the chartlink badge in the corner.

Data: 2 columns — constituency (string, "Constituency (ONS code or name)"), margin (number, "Winner's majority, % of votes cast") — and 650 rows in the example "How safe every seat was at the 2024 general election". Regions are named by ISO 3166-2 region codes or region names; a region with no row stays unfilled in grey, and an unknown code fails loudly with the nearest matches. Your data keeps the same column ids and every other setting comes from the template; an agent can change any of them.
