{"version":"1.0","type":"rich","title":"D3.js collapsible tree with boxes","description":"This interactive D3.js v3 visualization displays a hierarchical tree as a series of collapsible boxes, with each node representing a named entity and its associated link information. The tree layout is computed using `d3.layout.tree()`, and nodes are rendered as SVG rectangles with text, colored by a `type` property from the JSON data. Users can click nodes to collapse or expand branches, with smooth animations. The visualization also supports zooming and dragging via `d3.behavior.zoom()`, and includes tooltip boxes for additional details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f4e7cdbbea84e8984e2396bafd1eff1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
