Data-driven web maps based on D3 🗺️

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

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

Gridviz is a JavaScript library for visualizing gridded data (or any tabular dataset with x/y coordinates for that matter) in the browser using a large variety of cartographic styles and techniques. Unlike traditional raster-based web mapping tools, Gridviz renders everything client-side, on the…

🏄Windy API, or Windy Leaflet Plugin, let you put animated weather map into your website and enjoy rich ecosystem of Leaflet library.

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.

L7 is a WebGL-powered geospatial visualization engine and browser-based GIS engine designed for high-performance rendering of large-scale 2D and 3D spatial datasets. It functions as a geographic data visualization library that leverages hardware acceleration to display massive datasets and heatmaps within a web browser. The engine features an abstracted basemap integration layer that decouples data visualization from the underlying map provider, allowing for the use of various map providers or offline deployments. It employs a system for visual variable mapping to translate numeric and catego

Vue 2 components for Leaflet maps

Cesium is a JavaScript library designed for rendering high-precision 3D globes and 2D maps within web browsers. It functions as a visualization engine that leverages hardware-accelerated graphics to display complex geographic data, terrain, and imagery. The library distinguishes itself through a modular architecture that supports the streaming of massive geographic datasets. By employing tiled data delivery and hierarchical level-of-detail optimization, it maintains performance while navigating large-scale environments. It also includes a time-dynamic state management system, which synchroniz

Blazing Fast JavaScript Raster Processing Engine

gmaps is a library that provides a wrapper for the Google Maps API, serving as a geospatial data toolkit and interactive map renderer. It simplifies the integration of interactive maps into web applications by managing the embedding of map views and the lifecycle of markers. The project distinguishes itself through a specialized set of utilities for geocoding, which converts physical addresses to geographic coordinates and vice versa. It also includes a static map generator for creating non-interactive map images for lightweight environments. The capability surface covers geographic data vis
