Polymaps is a free JavaScript library for creating dynamic, interactive 'slippy' maps in modern web browsers using SVG. It extends the tile metaphor to vector graphics, supporting both image tiles (e.g., OpenStreetMap, Bing) and GeoJSON vector tiles rendered as SVG for rich, multi-scale data overlays.

Use cases

  • display interactive zoomable maps on a website
  • visualize large GeoJSON datasets as map overlays
  • render vector tiles with SVG and style them with CSS
  • build multi-scale maps from country level down to street level
  • overlay point clouds and county boundaries on image-based web maps

When to choose

  • you need SVG-based vector tile rendering with CSS styling
  • you want on-demand loading and caching of large geospatial datasets
  • you only need to support modern browsers with SVG support

When to avoid

  • you need broad legacy browser support (e.g., IE6)
  • you want a library with active ongoing development and community support
  • you need 3D maps or advanced features found in Leaflet or Mapbox GL
