{"version":"1.0","type":"rich","title":"Fork of Treemap","description":"This visualization shows a hierarchical treemap where rectangular tiles represent data categories, with size indicating their relative production values. The treemap displays five groups (grp1–grp7) nested under an origin node, each filled with a uniform teal color and labeled with white text. Built with D3 v6, the code uses `d3.stratify` to convert CSV data into a hierarchy, `d3.treemap` to compute tile positions, and SVG `rect` and `text` elements for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/32ce8c7487d4474fb80ce8b23571f39b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
