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.

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.
