# GoJS

A Web Framework for Rapidly Building Interactive Diagrams

View Samples Take the Tutorial

## GoJS 2.3 Beta – Featuring a new SVG rendering context. See the changelog for more details.

## Build Diagrams for the Web in JavaScript and TypeScript

### Flowcharts

Build interactive flowcharts or flow diagrams. Let your users build, modify, and save Diagrams with JSON model output.

### State Charts

Visualize State Charts and other behavior diagrams. Create diagrams with live updates to monitor state, or interactive diagrams for planning.

### Sankey Diagrams

GoJS allows considerable customization of Links and Nodes to build all kinds of diagrams. Visualize flow, or connect pipes.

### Genogram Diagrams

Create Genogram and Medical diagrams, or editable family trees with collapsible levels.

### Org Charts

Create classic org charts for viewing or editing. Automatic layouts make different visualization options easy.

### Dynamic Ports

Dynamically add ports and custom link routing. Use data-bindings to save and load routes within the Model JSON.

### Industrial Processes

Model industrial processes, workflows, SCADA diagrams and more. Permissions and validation make it easy to add rules and constraints when your users build diagrams.

### Dynamic Grouping

Use groups as containers and subgraphs, with group members bound by their own rules and layouts.

## Built-in features and interactivity to develop your projects faster

### Automatic Layouts

GoJS includes several built-in layouts, and many samples of custom layouts to be used or adapted.

### Node and Link Templates

Quickly set the look for your diagram parts while keeping appearance separate from data.

### Data Binding

GoJS models can automatically keep your data in sync with your display, and vice versa.

### Undo & Redo

GoJS has built-in state management to record a history of Diagram and Model changes. Users can easily undo and redo, and cancelled tool operations can be rolled back. This state can be inspected for futher customization.

### Keyboard Shortcuts

GoJS implements a number of common keyboard commands and gestures, which can be customized.

### Subgraphs

GoJS Groups provide subgraphs to apply different rules or layouts to their members.

### Extensible Tools

GoJS input is routed through tools that can be customized and extended to give your users the interaction they need.

### Customizable Events and Permissions

Execute custom logic or notifications when users do certain actions or key presses, or disable different interactions altogether.

### Context Menus and Tooltips

GoJS has built-in Context Menu and tooltips, which can be extended in-canvas or with HTML.

## Compatible with Modern Frameworks

We publish a React component, gojs-react to simplify React integration, and host a React sample using GoJS called gojs-react-basic. See the GoJS with React introduction page for more information.

We publish an Angular component, gojs-angular to simplify Angular integration, and host a Angular sample using GoJS called gojs-angular-basic. See the GoJS with Angular introduction page for more information.

We have a sample on using Vue.js with GoJS.
