About this template
Data: one row per region with its ISO 3166-2 code (IT-25 for Lombardy, IT-62 for Lazio) or its name, and a number. A region with no row stays grey. Same design as the other country maps, so they sit side by side.
A choropleth map of the states, provinces or regions of Italy (ISO 3166-2 codes), each region filled by one number from your data (the "population" column).
A sequential colour scale from pale blue for the smallest values to deep navy blue for the largest; pinned to 100000 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, "Region (ISO 3166-2 code or name)"), population (number, "Population, 1 January 2025") — and 20 rows in the example "Population of Italy's twenty regions, 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.
