{"version":"1.0","type":"rich","title":"Collapsible Tree Example","description":"This interactive collapsible tree diagram displays a hierarchical dataset with a top-level node branching into two second-level nodes and sub-nodes. Using D3 v6’s `d3.layout.tree` and `d3.svg.diagonal`, it renders nodes as white circles with steelblue strokes and connecting links, positioning them by depth. The SVG layout is fixed-depth, with nodes manually offset horizontally based on hierarchy level. The example’s markup references an Airbnb S-1 revenue dataset, but the code itself uses static inline tree data for the visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/59afaaf1145744e7bdf2bfff1cad40e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
