{"version":"1.0","type":"rich","title":"ICE8-Tree-CM","description":"A vertical D3.js tree visualizes programming languages across four layers: root, paradigm, language, and ecosystem. Color encodes paradigm (functional, object-oriented, procedural, scripting), while shape distinguishes each level—circle for root, diamond for paradigm, square for language, and triangle for ecosystem. Built with D3 v7 and SVG rendering, the tree includes hover tooltips, a legend, and inline self-tests calling `d3.stratify` to verify the data structure. The flat row data with parent-child IDs is converted into the tree layout, with accessible labels and ARIA attributes on the SVG element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/54bb0eaec2d64d77996db104e26cd207?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
