{"version":"1.0","type":"rich","title":"Heatmap","description":"This heatmap visualizes the wealth of billionaires across global regions and years, using a grayscale intensity scale where darker cells represent higher wealth values. The visualization arranges regions along the y-axis and years along the x-axis, with a legend showing the wealth-to-color mapping. Built with p5.js, the sketch loads data from a remote CSV file containing billionaire records, processes it in the `preload()` and `setup()` functions, and renders the heatmap using `rect()` calls with mapped fill colors. It also displays region and year labels alongside the interactive legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d49bf57d08614ed1a9d1628fe3deb04b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
