L7 is an open-source WebGL-powered geospatial data visualization engine from AntV (Ant Group) for rendering large-scale 2D and 3D map visualizations in the browser. It supports point, line, polygon, heatmap, and raster layers with data-driven visual mapping over multiple basemaps like Mapbox and AMap.

Use cases

• visualize millions of geo points on an interactive web map
• build 3D bar and arc maps for BI dashboards
• render heatmaps and grid aggregations of location data
• plot GeoJSON polygons and choropleth fills on a map
• create animated trajectory and route visualizations
• deploy offline/intranet map visualization apps

When to choose

• you need high-performance rendering of large-scale geospatial data in the browser
• you want rich map chart types (bubbles, arcs, heatmaps, 3D fills) with flexible data mapping
• you need multi-basemap support including AMap for China compliance and Mapbox for international use

When to avoid

• you need a full GIS desktop analysis tool rather than web visualization
• your project requires non-WebGL environments or server-side static map rendering
• you only need simple marker maps where a lighter library like Leaflet suffices
