Map of Iowa by county, one number per county

About this template

Data: one row per county in Iowa with its 5-digit FIPS code (19001 is the first) and a number; the name with the state ("Harris, TX" style) works too. A county with no row stays grey. The map is fitted to Iowa alone, so small counties read. Same design as the national county map and the other 49 state maps.

A choropleth map of the regions of the "us-counties-ia" geography, each region filled by one number from your data (the "income" column).

A sequential colour scale from pale blue for the smallest values to deep navy blue for the largest; pinned to 40000 to 150000, 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 as USD amounts, in compact form (1.2k, 3.4M), 0 decimals; on a white canvas (#ffffff) with near-black text — a light theme; 0.5-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 — county (string, "County (5-digit FIPS)"), income (number, "Average AGI per return ($)") — and 99 rows in the example "Average income per tax return by county in Iowa, 2021". 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.
