{"version":"1.0","type":"rich","title":"Tree","description":"A vertical family tree displays three generations of descendants from a single ancestor, with each node represented by a labeled circle. The visualization uses D3’s `d3.stratify()` to convert the flat `{child, parent}` data into a hierarchy, then applies the `d3.tree()` layout algorithm to position nodes top-down. Parent-child connections are drawn as paths using `d3.linkVertical()`, and the SVG output is rendered with the `join` API. The tree includes 36 individuals, branching into four main subfamilies.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bbba69144c584b53a39e608717426b53?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
