{"version":"1.0","type":"rich","title":"Family Tree","description":"This example displays a family tree as a hierarchical node-link diagram, with circles representing individuals and curved paths showing parent-child relationships. The color of each node indicates its generation depth, using red, blue, and green for successive levels. The code builds the structure from an array of parent-child pairs via `d3.stratify()`, then lays it out with `d3.tree()` and renders the result as SVG circles, paths, and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98da2d968fe046c9be47398c7bd68230?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
