{"version":"1.0","type":"rich","title":"AQI in America with Histogram","description":"This example combines a choropleth map of U.S. states with a histogram of air quality index (AQI) values over time. The map uses d3.geoAlbersUsa projection and d3.geoPath to draw state boundaries, with circles positioned by latitude and longitude and colored by a d3.scaleQuantile. The histogram below aggregates AQI readings by month using d3.histogram and d3.timeMonths, computing monthly means. Both visualizations are rendered as SVG within a React component, using data from a CSV file of ozone measurements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f6f90e657af4d71b859a0edf1e65d66?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
