{"version":"1.0","type":"rich","title":" Fork of D3 Starter","description":"This example visualizes a family tree as a static node-link diagram, using color-coded circles to show generational depth from root (red) to children (orange). The hierarchical data is defined as an array of node-parent pairs, then converted into a tree structure using the `d3.stratify()` API and laid out with `d3.tree()`. Links are drawn as lines, with nodes and labels rendered as SVG circles and text elements, all positioned using the computed layout coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
