{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"This example shows a hierarchical tree visualization of programming languages and their subcategories, with nodes colored by generation depth. The visualization uses D3 v7 and renders SVG elements, including vertical links drawn with `d3.linkVertical()` and nodes positioned via `d3.tree()`. The flat parent-child data is converted into a hierarchy using `d3.stratify()`. The root node appears in red, middle-level nodes in blue, and leaf nodes in green, with each node labeled by its name.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad6bb2637a8b42409c29bc111e6f4e1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
