{"version":"1.0","type":"rich","title":"Heatmap: Billionaires D3","description":"This heatmap visualizes billionaire wealth across regions and wealth types, with each cell colored by total wealth worth in billions and a tooltip displaying the exact value on hover. The chart uses D3 v6 with SVG rendering, employing `d3.scaleBand` for the x and y axes and `d3.scaleLinear` for the color mapping. Data is loaded from a CSV via `d3.csv`, and interactivity is handled through mouseover, mousemove, and mouseleave events that control a custom tooltip div. The visualization is titled and subtitled directly within the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd45bab710184f3297393b1696f66c3a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
