{"version":"1.0","type":"rich","title":"ICE-8-Q2.1-Tree-Basic","description":"This example shows a hierarchical tree of programming languages organized by paradigm, with four levels from root to leaf. It uses D3 v7’s `d3.hierarchy` and `d3.tree` layout with an SVG rendering approach, drawing horizontal links via `d3.linkHorizontal`. Nodes appear as blue circles with labels, and the layout adapts to an 800px-high viewBox, though the CSS height also adjusts to the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/79941029a1484f84b3aade0823c15d66?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
