Choropleths

Pass values keyed by ISO code. Six themes, three color scales, four classification strategies.

Markers & routes

Drop icons at lat/lon. Draw great-circle paths between cities. 30-icon library.

Cartographic polish

Region labels, north arrow, scale bar, graticule, legends. Pattern fills for disputed regions.

How it works

<img
  src="https://api.maproll.io/map.svg?scope=world&data=US:200,CN:150,DE:95&theme=dark"
  alt="World choropleth"
/>

Three params: scope, data, theme. Render is cached immutably, served behind Cloudflare, and embeds anywhere an <img> tag works — README, Notion, Slack, dashboards.
