GoJS, a JavaScript Library for HTML Diagrams

GoJS is a JavaScript and TypeScript library for creating and manipulating diagrams, charts, and graphs.

See GoJS Samples

Get Started with GoJS

GoJS is a flexible library that can be used to create a number of different kinds of interactive diagrams, including data visualizations, drawing tools, and graph editors. There are samples for flowchart, org chart, business process BPMN, swimlanes, timelines, state charts, kanban, network, mindmap, sankey, family trees and genogram charts, fishbone diagrams, floor plans, UML, decision trees, PERT charts, Gantt, and hundreds more. GoJS includes a number of built in layouts including tree layout, force directed, circular, and layered digraph layout, and many custom layout extensions and examples.

GoJS is renders either to an HTML Canvas element (with export to SVG or image formats) or directly as SVG DOM. GoJS can run in a web browser, or server side in Node or Puppeteer. GoJS Diagrams are backed by Models, with saving and loading typically via JSON-formatted text.

The GitHub repository and the GoJS website contain not only the library, but also the sources for all samples, extensions, and documentation.

However the npm package contains only the library. You can install the GoJS library using npm:

$ npm install gojs

The samples, extensions, and documentation can be installed by running:

$ npm create gojs-kit

You can use the GitHub repository to quickly search through all of the sources.

Minimal Sample

Diagrams are built by creating one or more templates, with desired properties data-bound, and adding model data.

<div id="myDiagramDiv" style="width:400px; height:200px;"></div>

The above diagram and model code creates the following graph. The user can now click on nodes or links to select them, copy-and-paste them, drag them, delete them, scroll, pan, and zoom, with a mouse or with fingers.
