{"version":"1.0","type":"rich","title":"AQI Data in America by county","description":"This interactive visualization displays a choropleth map of air quality index (AQI) data across U.S. counties, with each county colored by its AQI value according to a quantile scale. A brushed time-series histogram below the map filters the displayed data by collection date, allowing users to explore how AQI varies temporally. The map uses d3.geoPath with a geoAlbers projection and topojson county boundaries, while counties without data appear gray. The histogram is built with d3.bin and d3.brushX, and the entire interface is rendered as SVG within a React framework, reading from a CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bcd96fcff27147d798c5cd4c32fbe525?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
