Why Map Data

Everything you need to map your numbers

Bring your data any way you like, style it beautifully, and export it wherever you need it.

Bring any data

Import a CSV from your device or load one straight from a URL. Columns are auto-detected and matched to the right regions.

Ask AI for data

Describe what you want to map and let Anthropic, OpenAI, or Gemini fill in the values automatically — no spreadsheet required.

Accurate U.S. maps

All 50 states plus D.C. and every one of the 3,142 counties, drawn with a proper Albers USA projection and Alaska & Hawaii insets.

Style it your way

Multiple color palettes with quantile, equal-interval, or continuous scales — and clear, automatic legends every time.

Explore interactively

Pinch to zoom and pan smoothly across the map, and tap any region to reveal its exact value.

Export anywhere

Save your map as scalable SVG, print-ready PDF, shareable PNG, or export the joined data itself back out as CSV.

County-level detail, done right

Map all 3,142 U.S. counties at once. Map Data stitches and projects the geometry off the main thread, so panning and zooming stay smooth even at full county resolution.
