{"version":"1.0","type":"rich","title":"Fork of map of epa data sites","description":"This map visualizes U.S. EPA air quality site data, plotting circles for each location with a radius that encodes the AQI value. A geospatial projection via `d3.geoAlbersUsa` and `d3.geoPath` renders state boundaries from a TopoJSON US Atlas, while the circle sizes are scaled using `d3.scaleSqrt`. The React components load CSV data with `d3.csv` and render the SVG elements, with hover effects on states and semi-transparent blue circles marking the sites.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/08c0bf7b5f7641cabec5388135feaf4e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
