{"version":"1.0","type":"rich","title":"2nd task","description":"This treemap visualizes the distribution of billionaire wealth across twelve industries, using a color-coded hierarchy where rectangle size corresponds to total industry wealth. Built with D3 v7, the code uses `d3.hierarchy` and `d3.treemap` to compute spatial layout, then renders each leaf as an SVG `rect` with a text label. The visualization includes interactive tooltips that display the industry name and total wealth on hover, with smooth opacity transitions. The color scheme uses `d3.schemeSet3` for categorical distinction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8013bd3d9702458385d67dcb5cf67064?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
