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.

Minimal Sample

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

<div id="myDiagramDiv" style="width:400px; height:150px;"></div>

<script src="https://unpkg.com/gojs"></script>

<script>

const myDiagram =

  new go.Diagram("myDiagramDiv",  // create a Diagram for the HTML Div element

    { "undoManager.isEnabled": true });  // enable undo & redo

// define a simple Node template

myDiagram.nodeTemplate =

  new go.Node("Auto")  // the Shape will automatically surround the TextBlock

    // add a Shape and a TextBlock to this "Auto" Panel

    .add(new go.Shape("RoundedRectangle",

        { strokeWidth: 0, fill: "white" })  // no border; default fill is white

        .bind("fill", "color"))  // Shape.fill is bound to Node.data.color

    .add(new go.TextBlock({ margin: 8, stroke: "#333" })  // some room around the text

        .bind("text", "key"));  // TextBlock.text is bound to Node.data.key

// but use the default Link template, by not setting Diagram.linkTemplate

// create the model data that will be represented by Nodes and Links

myDiagram.model = new go.GraphLinksModel(

  [

    { key: "Alpha", color: "lightblue" },

    { key: "Beta", color: "orange" },

    { key: "Gamma", color: "lightgreen" },

    { key: "Delta", color: "pink" }

  ],

  [

    { from: "Alpha", to: "Beta" },

    { from: "Alpha", to: "Gamma" },

    { from: "Beta", to: "Beta" },

    { from: "Gamma", to: "Delta" },

    { from: "Delta", to: "Alpha" }

  ]);

</script>

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.
