Zero setup, 197 countries

Countries covered by the geo-atlas-data CDN mirror fetch straight from a plain browser — no proxy, no backend route, no CORS workaround.

Correctly wound, always

Every ring is validated and re-wound to RFC 7946 winding order before it reaches you, so d3-geo/react-simple-maps render it right the first time.

Two packages, one system

@geo-atlas/core fetches and normalizes the data. @geo-atlas/react wraps it in and useBoundaries() for a drop-in choropleth.

Framework-agnostic core

@geo-atlas/core has zero React dependency — use it directly in Node, SSR, or any other rendering layer.
