{"version":"1.0","type":"rich","title":"Fork of Fork of D3 Starter","description":"This example shows a family tree as a hierarchical node-link diagram, with color-coded nodes that distinguish generations: red for the root, blue for grandparents, green for parents, and orange for children. Using D3.js v7, it builds the hierarchy with `d3.stratify()` and lays it out with `d3.tree()`, then renders the structure as an SVG. The code draws black links as lines and labels each node with text, positioning all elements based on the computed tree coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
