Kepler.gl
Kepler.gl is a powerful, browser-based platform for visualizing large-scale geospatial data. It enables interactive exploration of location-based datasets through layered maps, dynamic filtering, and aggregation. Users can create heatmaps, point maps, and choropleth layers, and adjust visual properties such as color, size, and opacity in real time. Kepler.gl runs entirely in the browser, supporting high-performance rendering for large datasets without a backend server.
