{"version":"1.0","type":"rich","title":"q2","description":"This visualization displays average movie revenue per genre and year as a heatmap using D3 v7. The code builds a grid of colored rectangles from CSV data via `d3.csv` and `d3.rollups`, with a sequential color scale using `d3.scaleSequential` and `d3.interpolateRgb`. A gradient legend with an axis accompanies the SVG chart, and two buttons let viewers reorder rows alphabetically or by row mean using `d3.axisLeft` and `d3.axisBottom`. The data comes from a gist-hosted CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1674f182593f473ca33405f059168ef0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
