{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive visualization displays a hierarchical tree as a circular packing layout, where nodes are sized proportionally to their values. The code uses the D3.js library (v6.7.0) with its `pack` and `hierarchy` APIs to compute node positions, and transitions to animate changes. Clicking a parent node collapses or expands its children, triggering a re-layout. The SVG renders nodes as circles with labels, and blue directed links with arrowheads connect specific nodes across the hierarchy, based on a `links` array in the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce13a955b71c473cab5d6524f7d63020?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
