{"version":"1.0","type":"rich","title":"tree diagram","description":"A hierarchical tree diagram organizes programming languages into a root, categories, and individual languages. Each level is distinguished by a unique color, with nodes and labels displayed across a horizontal layout. The visualization uses D3.js v7, specifically the `d3.stratify` and `d3.tree` APIs to structure and position the hierarchy. Links are drawn with `d3.linkHorizontal`, and nodes are circles colored by depth, rendered as SVG within a `viewBox` canvas. A small legend clarifies the color mapping for root, category, and language depths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/70b5a0eebb2a449bb49ae95b2d01b80c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
