{"version":"1.0","type":"rich","title":"Tree Map","description":"This tree map displays hierarchical data as nested rectangles sized proportionally to their values. The example renders an SVG graphic at 960 by 500 pixels, pulling in D3 v5 from a CDN. The code imports `select` and `arc` from the D3 library, though the visualization logic itself remains minimal in the shown files. The page references a separate stylesheet and JavaScript bundle, with the SVG container set up for the treemap layout. The map is generated using D3’s standard tree-map approach, though the actual data and layout calculations are not explicitly defined in the visible code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be960bdb9448497998b8fa7d65e44ea0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
