{"version":"1.0","type":"rich","title":"ICE 8 tree","description":"This example displays a three-level hierarchical tree of programming languages, grouped by paradigm (Object-Oriented, Functional, Scripting). The SVG visualization uses color-coded nodes—orange for the root, blue for paradigm categories, and green for individual languages—with horizontal links. The code builds the hierarchy using `d3.hierarchy()` and applies a tree layout, drawing connections with `d3.linkHorizontal()` and labeling nodes via appended SVG text elements. The data is a static JSON object embedded in the script, with all elements rendered directly into an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a946097cd3814c3096cf35ffa597401d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
