{"version":"1.0","type":"rich","title":"Rounded Groups With a Header and a Footer","description":"This example shows a tree diagram where nodes are grouped into containers, each with a header, a body, and a footer. The container’s header and footer use custom GoJS shapes, `RoundedTopRectangle` and `RoundedBottomRectangle`, from the `RoundedRectangles` extension, while the body holds child nodes via a `Placeholder`. Node templates similarly combine these shapes to display role-based coloring and optional loop indicators using `BpmnActivityLoop`. The diagram uses `go.TreeLayout` for automatic positioning, and links are drawn with orthogonal routing and triangular arrowheads. Data is provided as a static JSON-like array of nodes and groups.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d08086d39cb4c218ed5860b399186ed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
