{"version":"1.0","type":"rich","title":"Fork of AQI Data in America by county","description":"A choropleth map of the United States displays county-level AQI values, colored with a quantile scale across a green-to-red gradient, with gray for missing data. A date histogram below (though not rendered in the visible SVG) is intended to show AQI trends over time. Built with React and D3 v5, the map uses `d3.geoAlbers` and `d3.geoPath` to draw county boundaries from TopoJSON, while `d3.csv` loads the air quality dataset and `d3.scaleQuantile` assigns colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/02a4ffe5a4dc40f0b7eccb3b6dec59a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
