antvis L7

Leverages WebGL for integrated 2D and 3D rendering, enabling real-time visualization of massive spatial datasets with interactive capabilities, as highlighted in the core features.

Supports CSV, JSON, GeoJSON, and custom formats without complex spatial data conversion, simplifying data ingestion from diverse sources as mentioned in the README.

Provides numerous visualization layers including point, line, polygon, heatmap, and raster types, allowing for diverse map chart creation and better data insight.

Works with Gaode for China and Mapbox internationally, abstracting basemap differences and supporting offline deployment, so developers can focus on data layer expression.
