{"version":"1.0","type":"rich","title":"Fork of Fork of Fork 1","description":"A static tree diagram called \"Fork of Fork of Fork 1\" visualizes a three-level hierarchy of car types. The root node \"Car Types\" branches into three transmission categories—Automatic, Manual, and Semi-Automatic—each with children representing door counts. Built with D3.js v7, the example uses `d3.tree()` and `d3.hierarchy()` to compute node positions, drawing horizontal links with `d3.linkHorizontal()`. Nodes are custom-styled: the root as a purple rectangle, depth-1 nodes as blue circles, and leaf nodes as orange diamonds. Although the code loads a CSV dataset, the displayed tree uses a hardcoded structure rather than the fetched data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98fe103eb0534174a7747ab44a486d89?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
