{"version":"1.0","type":"rich","title":"ICE-8 2q tree","description":"This example shows a hierarchical tree of programming languages organized top-down, with root, category, subcategory, and leaf nodes distinguished by color. The visualization uses D3.js v7’s `d3.hierarchy` and `d3.tree` layouts to compute positions, then renders SVG paths via `d3.linkVertical` and circles with text labels. Node colors vary by depth, and hover interactions thicken circle strokes. The data is hardcoded in JavaScript with categories like Procedural, Object-Oriented, and Functional, each branching into specific languages.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/863540352e764e799e45cad46aaf132c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
