{"version":"1.0","type":"rich","title":"Vinay Tree Vizualization","description":"This example shows a family tree as a hierarchical node-link diagram, with color-coded circles representing generations: red for the grandparent, orange for the parent level, and green for descendants. Using D3 v7, the code applies `d3.stratify` to convert the flat array of family relationships into a tree structure, then lays it out with `d3.tree` and renders vertical links via `d3.linkVertical`. Nodes are drawn as SVG circles with text labels above them.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2320350300f149c28f598ba104a4dc2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
