Map of Maryland by ZIP code, one number per ZIP code

About this template

Data: one row per 5-digit ZIP code in Maryland (as text — keep leading zeros) and a number. A ZIP code with no row stays grey; ZIP codes with no residents (large parks, water) are not drawn. The map is fitted to Maryland alone. Same design as the state's county map and the other 49 ZIP maps.

A choropleth map of the 5-digit ZIP codes of Maryland (Census ZIP Code Tabulation Areas), each region filled by one number from your data (the "income" column). The borders of the "us-states-outline" regions are drawn on top of the regions in dark navy blue, 1 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 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; 0.25-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 — zip (string, "ZIP code (5 digits)"), income (number, "Average AGI per return ($)") — and 403 rows in the example "Average income per tax return by ZIP code in Maryland, 2021". Regions are named by 5-digit ZIP codes; 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.
