Sigma.js
sigma.js is a JavaScript graph visualization library and WebGL network renderer designed for drawing large-scale network graphs in web browsers. It functions as a high-performance engine capable of rendering network structures containing thousands of nodes and edges interactively.
The library provides a customizable graph engine that allows for the creation of specialized visualizations using low-level graphics primitives and custom drawing layers. It supports the rendering of diverse node shapes, such as images or piecharts, and enables the integration of graph visualizations as overlays on interactive geographic maps.
The toolset includes capabilities for interactive network analysis and data visualization, including utilities to export the current state of a graph instance as a static image file.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
