About this template
Data: one row per région with its NUTS 2024 code (FR1 for Île-de-France, FRK for Auvergne-Rhône-Alpes) or its name — in the local language or in English — and a number. A région with no row stays grey. The frame shows metropolitan France; the overseas régions take their row but sit outside it. Same design as the other country maps.
A choropleth map of the regions of the "fr-nuts1" geography, each region filled by one number from your data (the "population" column). The view is cropped to longitude -5–9.8 and latitude 41.3–51.2.
A sequential colour scale from pale blue for the smallest values to deep navy blue for the largest; pinned to 2500000 to 10000000, 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 in compact form (1.2k, 3.4M), 1 decimal; on a white canvas (#ffffff) with near-black text — a light theme; 0.6-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 — region (string, "Région (NUTS code or name)"), population (number, "Population, 1 January 2025") — and 14 rows in the example "Population of France's régions, 2025". 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.
