{"version":"1.0","type":"rich","title":"D3.js collapsibleRRR tree with boxes","description":"A hierarchical tree visualization displays nested nodes as labeled boxes, with colored types (blue, green, yellow, purple) and tooltips on hover. Built with D3.js v3, the SVG-based layout uses the custom `treeBoxes` function and `d3.layout.tree` to position nodes, while interactive zooming, dragging, and collapsible branches are enabled through `d3.behavior.zoom` and click handlers. The example loads JSON data from `data-example.json` and renders it as an interactive, animated tree.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/367da5345ce1466087463f0e006657c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
