{"version":"1.0","type":"rich","title":"Fork of Heatmap: Billionaires D3","description":"This fork of the Billionaires D3 example displays a heatmap where each cell’s color intensity, using the Inferno interpolator via `d3.scaleSequential`, encodes a numeric value from a CSV file. The chart renders as an SVG with `d3.axisBottom` and `d3.axisLeft` for the categorical group and variable axes. Interactive tooltips are created with a `div` element and updated through `mouseover`, `mousemove`, and `mouseleave` events, showing the exact value of the hovered cell. The code uses D3 v6 and loads external data from GitHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5cb54096caa46cea4de332023facf9d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
