{"version":"1.0","type":"rich","title":"Tree Diagram","description":"This tree diagram visualizes a small, three-level dataset of animals, showing the hierarchical structure from the root \"Animals\" through categories like \"Mammals\" and \"Birds\" down to individual species. Nodes are drawn as colored circles, with a distinct color per depth level, connected by horizontal links. The example uses D3 v7 APIs including `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and `d3.scaleOrdinal`, with SVG rendering for all elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/92ed3b3e827441d994d9fac33283a385?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
