GoJS is a feature-rich JavaScript library for implementing interactive diagrams across modern browsers and platforms. GoJS makes constructing diagrams of complex Nodes, Links, and Groups easy with customizable templates and layouts.

GoJS offers many advanced features for user interactivity such as drag-and-drop, copy-and-paste, transactional state and undo management, palettes, overviews, data-bound models, event handlers, and an extensible tool system for custom operations.

GoJS is pure JavaScript and it does not depend on any JavaScript libraries or frameworks. Users get interactivity without requiring round-trips to servers and without plugins such as Flash or Silverlight.
