View Samples Take the Tutorial
Diagram

January 2022: GoJS 2.2 has been released! See changelog here

Build Diagrams for the Web in JavaScript and TypeScript

Flowchart

Flowcharts

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

State Charts

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

Sankey Diagrams

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

Genogram Diagrams

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

Org Charts

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

Dynamic Ports

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

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.
Regrouping Demo

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

react angular vue

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.
