L7 is a WebGL-based engine for visualizing large-scale geospatial data, including points, lines, polygons, heatmaps, and 3D city scenes on maps like Gaode or Mapbox.

The skill guides your AI agent to create a Scene, load GeoJSON through a parser, and add the right layer type with color and size mappings automatically.

Yes. The skill includes strict React best practices for single map initialization, layer updates, and proper cleanup to prevent duplicate scenes and memory leaks.

Use Marker for fewer than 100 points with custom HTML, and PointLayer for large datasets that need high-performance WebGL rendering.
