harp.gl is an experimental and work in progress open-source 3D map rendering engine written in TypeScript.

Datamaps is a library for generating interactive, data-driven geographic visualizations within web applications. It utilizes scalable vector graphics to render maps, allowing for precise styling and responsive resizing across different screen sizes. The library provides a declarative configuration pattern that binds custom datasets to geographic regions. This enables the creation of choropleth maps, where regions are color-coded based on statistical values, and point-based overlays that represent individual data points as interactive bubbles. Beyond basic rendering, the toolset includes capa

TopoJSON is an extension of GeoJSON that encodes topology. Rather than representing geometries discretely, geometries in TopoJSON files are stitched together from shared line segments called arcs. This technique is similar to Matt Bloch’s MapShaper and the Arc/Info Export format, .e00.

Cesium is a JavaScript geospatial visualization library and 3D globe engine designed to render world-scale environments and precision spatial data. It functions as a web-based mapping tool that displays hardware-accelerated 3D globes and 2D maps directly in a browser without requiring external plugins. The project operates as a 3D tiles renderer, utilizing the 3D Tiles open standard to stream and display large-scale geospatial datasets. It enables the visualization and analysis of high-accuracy spatial information across global environments. The library covers a broad range of capabilities,
