{"version":"1.0","type":"rich","title":"Fork of Fork of AQI Data in America by State","description":"A choropleth map of the United States colors each state by its average Air Quality Index (AQI), using a quantile color scale with eight green-to-red bins. A white fill marks states without data. The visualization pairs the map with a time-series histogram showing monthly mean AQI values, though the histogram is not visible in the final render. Built with React and D3 v5, the map uses `d3.geoAlbersUsa` and `d3.geoPath` to project TopoJSON state boundaries from the us-atlas package, while the histogram applies `d3.bin` and `d3.brushX` for interactive filtering of the map by date range. Data comes from a CSV of ozone measurements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/30cc25831cfa4e42a26d64ef74328fed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
