{"version":"1.0","type":"rich","title":"Fork of ice8","description":"This interactive tree diagram displays a family hierarchy loaded from a JSON file, with nodes labeled by names and connected by curved links. Users can click any node to collapse or expand its subtree, with smooth 1.1-second transitions animating nodes and links to new positions. The visualization uses D3.js v3’s `d3.layout.tree` for layout and `d3.svg.diagonal` for link paths, rendered as SVG with green-bordered circles and bold text labels. Node expansion state is managed by toggling between `children` and `_children` arrays.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/725a96ff517d415d91f1e713884d129d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
