Open-source alternatives to React Azure Maps

This module uses spherical GeoJSON to represent geographic features in JavaScript. D3 supports a wide variety of common and unusual map projections. And because D3 uses spherical geometry to represent data, you can apply any aspect to any projection by rotating geometry.

Extended geographic projections for d3-geo.

Maplibre GL JS is a WebGL map rendering engine and vector tile map library used to create interactive web maps. It serves as a web-based GIS visualization tool and an interactive map interface framework for rendering geographic data and vector tiles on web pages. The library provides capabilities for 3D terrain rendering and the integration of custom 3D content. It supports complex geospatial data visualization through the use of heatmaps, clusters, and 3D extrusions, while allowing for custom map styling and environmental effect customization. The system covers a broad range of functional a

maptalks.js is a JavaScript map rendering library and web map interaction framework used to render interactive 2D and 3D geographic data on a web canvas. It functions as a 3D geospatial engine supporting 3DTiles and GLTF formats, a GeoJSON visualization tool, and a spatial analysis library. The project distinguishes itself through high-performance rendering and dynamic geospatial animation, including the ability to simulate traffic flow and execute smooth visual transitions for map elements. It provides comprehensive tools for interactive geometry editing, allowing users to draw and modify ve

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

Bertin.js is a JavaScript library for visualizing geospatial data and make thematic maps for the web.
