{"version":"1.0","type":"rich","title":"Fork of AQI Data in America by county","description":"This visualization shows the Air Quality Index (AQI) across American counties using a choropleth map, with each county colored on a quantile scale from green to red based on PM2.5 concentrations. The map is rendered as SVG using React and d3.geoAlbersUsa projection, with d3.geoPath drawing county boundaries from TopoJSON data. County-level pollutant data is loaded from a CSV file, and counties with missing data appear in grey. The color scale d3.scaleQuantile maps AQI values to a eight-color gradient, with d3.geoMesh rendering state interiors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/873876718a4d4f37a73a427971f1fe8a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
