{"version":"1.0","type":"rich","title":"Fork of map of epa data sites","description":"This visualization displays the locations of EPA air quality monitoring sites across the United States, with each site represented by a circle sized according to its AQI value. The map uses a d3.geoAlbersUsa projection and d3.geoPath to render state boundaries and interiors from a TopoJSON US Atlas, while circles are positioned using longitude and latitude coordinates. The React-based BubbleMap component integrates d3.scaleSqrt to map AQI values to a maximum radius of 5 pixels for the bubble marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
