{"version":"1.0","type":"rich","title":"Tree Example","description":"This interactive tree diagram displays a three-generation family lineage, using an animated collapsible hierarchy. The visualization is built with the D3.js library (version 3.5.17) and renders as SVG, using the `d3.layout.tree` for layout computation and `d3.svg.diagonal` for curved link paths. Nodes are white circles with steel blue strokes, and clicking a node toggles its children’s visibility, smoothly transitioning positions via `node.transition()` and `link.transition()` over 750 milliseconds. The data is hardcoded in the script as a JSON array, with each node containing a name and parent reference.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9fc515a4309e4fe898d3860d33487cc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
