{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"A tree diagram displays a three-level programming language hierarchy, from a root node to category nodes for Frontend, Backend, and Data Science, each with leaf-node languages. The visualization uses D3.js v7 to build the SVG layout, with `d3.hierarchy` and `d3.tree` computing positions. Node shapes encode type: rectangles for root, circles for categories, and rotated squares for leaves, all connected by `d3.linkHorizontal` paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3bd45cd176b54c219ef81a922c94ef74?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
