Kepler.gl, an open-source geospatial visualization tool, is gaining traction on Hacker News. A new open-source map editor, "insight-editor," built on top of Kepler.gl with DuckDB integration, was recently released. DuckDB is highlighted as a game-changer for geospatial visualization because it enables client-side processing of massive datasets. Foursquare's SQLRooms, another open-source project powered by DuckDB and deck.gl, is also mentioned. A comment pointed out that real decisions often rely on simple text or numbers, not necessarily visualizations and visualizations are supporting tools. A contributor mentioned a collaborator summit for Kepler.gl and deck.gl this fall in Seattle, supported by the OpenJS Foundation, and featuring sessions from the creators of Kepler.gl and SQLRooms. Some find Kepler.gl a potentially more accessible alternative to CARTO, while others noted that CARTO focuses on backend pipelines for large-scale data, which Kepler.gl may not handle as effectively. However, CARTO's engineering team actively contributes to deck.gl, powering Kepler.gl.
