One library for every possibility

GoJS is used for a wide range of supervising, control, and editing. Samples below demonstrate a few possibilities.

GoJS is often used for flowcharts, process demonstrations, low-code and no-code tools, and more.

Let users wire triggers, prompts, tools, and conditions into a graph that your runtime executes. Constrain what can connect to what.

GoJS is used for HR and workforce visualization and planning. Add, remove, and reassign people with a context menu and inline editing.

Visualize relationship and medical data across generations.

Enforce rules for users to create logically correct diagrams.

Drag nodes, including groups, into and out of groups. GoJS lets you collapse and expand groups, and give them their own subgraph layouts.

Built in

The parts you would otherwise have to build yourself

Automatic layouts: Arrange a process top-down or left-to-right with LayeredDigraphLayout, or an org chart of thousands of people with TreeLayout. Each has dozens of options for spacing, alignment, and ordering.
Ports and link validation: Decide where links may start and end, cap how many connect to each port, and reject invalid connections while the user is still drawing them.
Undo and redo: Every edit runs in a transaction, so undo and redo work out of the box, including cancelled drags and text edits.
Groups and subgraphs: Containers that move, copy, and delete with their contents. Use them as subgraphs, phases, or departments, give each its own layout, and let users collapse them.
Collapse, expand, and reassign subtrees: Built-in expand and collapse for both groups and graph subtrees. Drag a node onto a new manager to move its entire team.
JSON in, JSON out: Models hold only your data, saving and loading as JSON by default. Keep node and link data in whatever shape your backend already uses, and bind templates to it.
