{"version":"1.0","type":"rich","title":"Treemap example","description":"This treemap presents the populations of ten countries, with each rectangle’s width proportional to its population and the height divided equally. The visualization uses a bar-chart layout rather than a nested treemap, with countries listed on the y-axis and population values on the x-axis. Built with D3 v5, the code loads data from `data.csv` and draws SVG rectangles using `scaleLinear` and `scaleBand` scales, with axes rendered via `axisLeft` and `axisBottom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a1d37e3e2e8490cbc87528c197cb2fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
