{"version":"1.0","type":"rich","title":"Family Tree","description":"A family tree visualization displays hierarchical parent-child relationships across four generations, with nodes colored by depth and labeled with character names. Each connection animates from a horizontal line into a diagonal link as the tree expands. The implementation uses D3 v6’s `d3.stratify()` to build the hierarchy from flat data and `d3.tree()` to compute layout positions, while SVG circles, text, and paths are rendered with transitions on `attr` for smooth node growth and link drawing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad11642cf56a45548aab148ab6bc829d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
