{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example shows a three-generation family tree with colored nodes representing grandparents, parents, and children, connected by curved links. The code converts flat family data into a hierarchy using `d3.stratify`, then lays it out with `d3.tree()`. Nodes are rendered as SVG circles with name and generation labels, while links use `d3.linkVertical()` to draw the connections. A `d3.scaleOrdinal()` maps generations to distinct colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3d0bbbd389b440a847d9bf708a99558?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
