{"version":"1.0","type":"rich","title":"Fork of Tree","description":"This interactive visualization displays a collapsible tree of programming languages organized across four layers: root, paradigm, family, and language. Using D3 v7’s `d3.hierarchy` and `d3.tree` layouts, nodes render as distinct SVG symbols (star, triangle, square, circle) with colors varying by depth. Clicking nodes collapses or expands branches, with `transition` animations smoothly redrawing link paths and node positions. The initial view collapses nodes at depth ≥2, showing only paradigms and families until expanded.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1c1cd50d9fef4ec7bd9ae2adf6a17cab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
