{"version":"1.0","type":"rich","title":"Tree graph","description":"A tree graph displays hierarchical data as connected nodes branching from a single root. The visualization uses a force-directed layout via `d3.forceSimulation` to position nodes, with links drawn as curved paths. Nodes are rendered as circles colored by depth, and the graph updates smoothly through D3’s `transition` when re-simulated. The code loads a JSON dataset and relies on `d3.hierarchy` and `d3.tree` to compute the tree structure before applying the force simulation for final placement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74544217c0d84584aa7824e018dd290d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
