Kepler.gl is a tool designed for geospatial data analysis.  Kepler.gl will prompt you to add data to your map as soon as you open the web page. Upload your own CSV or GEOJSON file, or add kepler.gl sample data. Sample data is a great way to explore and get familiar with kepler.gl’s features.

Open the Data Layers menu to start building your visualization. Layers are simply data visualizations that can be built on top of one another. The map pictured above contains a GeoJSON path layer showing trip routes. Layers of the same type can differ greatly in appearance depending on how they’re configured, opening up new possibilities for data analysis.
