{"version":"1.0","type":"rich","title":"family tree 8.2","description":"A family tree of programming domains is shown as a vertical hierarchy, with colored nodes representing technology categories (Technology, Software, Hardware, AI) and their subcategories. The visualization uses D3.js v7's `d3.stratify()` to convert flat parent-child data into a hierarchy, then positions nodes with the `d3.tree()` layout. Links are drawn as vertical paths using `d3.linkVertical()`, while circles and text labels are placed at computed coordinates. The data is a static array of programming domains, rendered as an SVG with colored nodes by depth level.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16d17a6511c047baaf0f56df9e2ab033?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
