{"version":"1.0","type":"rich","title":"A4 Heat Map in D3","description":"This heat map displays the number of police shootings across 20 US cities, using a single row of rectangles colored from white to red to represent low to high incident counts. Built with D3 v7 and React, it reads CSV data from a GitHub gist and uses `d3.rollup` for aggregation, `d3.scaleBand` for horizontal positioning, and `d3.scaleLinear` for the color mapping. The visualization includes a rotated x-axis with city labels and renders entirely as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3eebd19fecf446bab8430751c960670e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
