{"version":"1.0","type":"rich","title":"Fork of map of epa data sites","description":"This map plots EPA air quality monitoring sites across the United States, with each site represented by a circle at its geographic coordinates. The visualization uses `d3.geoAlbersUsa` projection with `d3.geoPath` to render state boundaries and interiors as SVG paths, while React manages the component hierarchy. The site data, loaded via `d3.csv`, includes latitude, longitude, and AQI values, though the circle radius is currently fixed at 5 pixels despite a `scaleSqrt` being configured. The map uses a teal color scheme for states with light gray interior borders, and semi-transparent blue circles for the monitoring locations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef9a58f9791349978164fb9bd8003b0a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
