{"version":"1.0","type":"rich","title":"D3.js collapsible tree with boxes","description":"This is a radial collapsible tree visualization built with D3.js v3, displaying a hierarchical dataset of High Conservation Value Areas (HCVAs) in Sikkim. The tree branches outward from a central root node, with circular node markers and text labels arranged in a circular layout. The visualization uses `d3.layout.tree` and `d3.svg.diagonal.radial` to position nodes and draw connecting links, with node positions computed via rotational transforms. The dataset is loaded from a JSON file using `d3.json`, and the layout supports hierarchical nesting up to three levels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c29a74e3ea2412c88281a12c0215aff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
