{"version":"1.0","type":"rich","title":"AQI data in America over histogram","description":"This visualization maps Air Quality Index (AQI) data across the United States, displaying each monitoring site as a circle sized proportionally to its AQI value. The map uses a `geoAlbersUsa` projection and `geoPath` to render state boundaries from TopoJSON, while circles are scaled with `scaleSqrt` on a dataset from a CSV file. The React-based interface integrates D3 v5 for data loading and map rendering, with SVG elements providing a clear, interactive view of regional air quality variations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b81278b01da434db140ede8128b4734?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
