GoJS a JavaScript Library for HTML Diagrams


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. GoJS includes a number of built in layouts including tree layout, force directed, radial, and layered digraph layout, and a number of custom layout examples.

GoJS is rendered with an HTML Canvas element (with export to SVG or image formats). 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.

This repository contains both the library and the sources for all samples, extensions, and documentation.
You can use the GitHub repository to quickly search through all of the sources.

Minimal Sample


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

  1. ```html
  2. <div id="myDiagramDiv" style="width:400px; height:150px;"></div>
  4. <script src="https://unpkg.com/gojs"></script>
  6. <script>
  7. const myDiagram =
  8.   new go.Diagram("myDiagramDiv",  // create a Diagram for the HTML Div element
  9.     { "undoManager.isEnabled": true });  // enable undo & redo
  11. // define a simple Node template
  12. myDiagram.nodeTemplate =
  13.   new go.Node("Auto")  // the Shape will automatically surround the TextBlock
  14.     // add a Shape and a TextBlock to this "Auto" Panel
  15.     .add(new go.Shape("RoundedRectangle",
  16.         { strokeWidth: 0, fill: "white" })  // no border; default fill is white
  17.         .bind("fill", "color"))  // Shape.fill is bound to Node.data.color
  18.     .add(new go.TextBlock({ margin: 8, stroke: "#333" })  // some room around the text
  19.         .bind("text", "key"));  // TextBlock.text is bound to Node.data.key
  21. // but use the default Link template, by not setting Diagram.linkTemplate
  23. // create the model data that will be represented by Nodes and Links
  24. myDiagram.model = new go.GraphLinksModel(
  25.   [
  26.     { key: "Alpha", color: "lightblue" },
  27.     { key: "Beta", color: "orange" },
  28.     { key: "Gamma", color: "lightgreen" },
  29.     { key: "Delta", color: "pink" }
  30.   ],
  31.   [
  32.     { from: "Alpha", to: "Beta" },
  33.     { from: "Alpha", to: "Gamma" },
  34.     { from: "Beta", to: "Beta" },
  35.     { from: "Gamma", to: "Delta" },
  36.     { from: "Delta", to: "Alpha" }
  37.   ]);
  38. </script>
  39. ```

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.
