    Sigma.js

    Website | Documentation | Storybook


    Sigma.js is an open-source JavaScript library aimed at visualizing graphs of thousands of nodes and edges using WebGL, mainly developed by @jacomyal and @Yomguithereal, and built on top of graphology.

    How to use in your project

    To integrate sigma into your project, follow these simple steps:

    1. Installation: Add sigma and graphology to your project by running the following command:

      npm install sigma graphology
      
    2. Usage: Import sigma into your JavaScript or TypeScript file:

      import Graph from "graphology";
      import Sigma from "sigma";
      

      Then, create a new Sigma instance with your graph data and target container:

      const graph = new Graph();
      graph.addNode("1", { label: "Node 1", x: 0, y: 0, size: 10, color: "blue" });
      graph.addNode("2", { label: "Node 2", x: 1, y: 1, size: 20, color: "red" });
      graph.addEdge("1", "2", { size: 5, color: "purple" });
      
      const sigmaInstance = new Sigma(graph, document.getElementById("container"));
