Datamaps is a JavaScript library for creating customizable, interactive SVG map visualizations (choropleths, bubble maps, arcs) bundled into a single script file built on D3.js and Topojson. It scales to any screen size and supports custom map data and plugins for additional visualization types.

Use cases

• render a world choropleth map colored by country data
• show bubble markers on a USA map for city-level metrics
• draw arcs between geographic points on a map
• embed an interactive scalable SVG map in a web dashboard
• create custom map visualizations with a plugin system
• animate geographic data over time on a map

When to choose

• you need lightweight, dependency-simple SVG maps in a single JS file
• you want choropleth or bubble maps without a full mapping framework
• you need maps that scale responsively in the browser
• you want to extend maps with custom visualization plugins

When to avoid

• you need street-level or tile-based maps like Leaflet or Mapbox
• you need actively developed features or timely bug fixes
• you need WebGL performance for very large datasets
• you need built-in support for scopes beyond world/USA without custom map data
