A Web Framework for Rapidly Building Interactive Diagrams
January 2022: GoJS 2.2 has been released! See changelog here
Build interactive flowcharts or flow diagrams. Let your users build, modify, and save Diagrams with JSON model output.
Visualize State Charts and other behavior diagrams.
Create diagrams with live updates to monitor state, or interactive diagrams for planning.
GoJS allows considerable customization of Links and Nodes to build all kinds of diagrams. Visualize flow, or connect pipes.
Create Genogram and Medical diagrams, or editable family trees with collapsible levels.
Create classic org charts for viewing or editing. Automatic layouts make different visualization options easy.
Dynamically add ports and custom link routing. Use data-bindings to save and load routes within the Model JSON.
Model industrial processes, workflows, SCADA diagrams and more. Permissions and validation make it easy to add rules and constraints when your users build diagrams.
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
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.
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.
GoJS implements a number of common keyboard commands and gestures, which can be customized.
GoJS Groups provide subgraphs to apply different rules or layouts to their members.
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.
Start from over 200 sample apps that demonstrate flowcharts, org charts, mind maps, UML diagrams, BPMN diagrams, graph editors, data visualization, custom tools and layouts, and much more.
