{"version":"1.0","type":"rich","title":"Fork of Tree_hd","description":"This example shows a hierarchical tree of programming paradigms—object-oriented, functional, and procedural—with nested subcategories leading to specific languages. Node shapes encode depth: a star marks the root, diamonds level 1, triangles level 2, and squares level 3 leaves. The code uses `d3.hierarchy` and `d3.tree` to compute the layout, `d3.linkVertical` for curved links, and SVG paths for custom node shapes. A legend clarifies the shape-to-level mapping, while an ordinal color scale differentiates depths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7241ee89b9f4479caf9dcb08f194b24e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
