{"version":"1.0","type":"rich","title":"Force-Directed Graph: Collapsible, Hierarchical","description":"This example shows a hierarchical force-directed graph of the Flare software package’s class hierarchy, where collapsible nodes reveal or hide their children. The visualization uses d3.layout.force for physics simulation, with node size encoding the `size` attribute from the flare.json data source and color distinguishing leaf nodes from internal ones. Rendering is done with SVG circles and lines, animated on each tick. Clicking a node toggles its children, and custom constraints in the tick handler enforce a vertical hierarchy where child nodes remain below their parents.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd8a55b40cf749b0b53aacd341b2dcbe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
