{"version":"1.0","type":"rich","title":"AQI Data in America by State","description":"A choropleth map of the United States colors each state by its average Air Quality Index (AQI) value, using a quantile color scale ranging from green to red. A linked time-series histogram below displays monthly mean AQI values, with a brushable interface that filters the map’s state colors based on the selected date range. The visualization uses React and D3 v5, with `d3.geoAlbersUsa` and `d3.geoPath` for map rendering and `d3.brushX` for interactive filtering. Data comes from a CSV of ozone samples collected nationwide.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/425368feeb7e48f98423310c1d8ea8e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
