{"version":"1.0","type":"rich","title":"map with aqi data","description":"This map displays air quality index (AQI) readings as circles overlaid on a U.S. states map, with circle size proportional to AQI values. It renders SVG via React, using d3.geoPath with a geoAlbersUsa projection for the map outlines and d3.scaleSqrt to map AQI to radii. The data is loaded as CSV from a GitHub gist, while state boundaries come from the us-atlas TopoJSON. Hovering over a circle shows a tooltip with its AQI value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1cbc96492c4d42b1a79cd6f8760f705e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
