{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows an interactive force-directed graph of hierarchical data from a JSON file, where nodes represent categories and files, and links show parent-child relationships. Users can collapse or expand nodes by clicking, which restarts the layout simulation. The visualization uses the `d3.layout.force` API to compute node positions and link distances, with node size mapped from the data’s `size` attribute. Rendering is done via SVG, with circle styling and text labels per node, and the color function distinguishes collapsed, expanded, and leaf nodes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3405ed6db6684e6f93caa756f8c67080?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
