{"version":"1.0","type":"rich","title":"Untitled","description":"This example combines a U.S. state map with a date-based histogram, visualizing ozone AQI values from a cleaned CSV dataset. The map renders state boundaries and interiors using `d3.geoPath` and `topojson` features. A histogram of daily AQI readings is drawn with React and D3 scales, where each bar’s tooltip displays its exact AQI value. The code uses `d3.csv` for data loading and `d3.json` for the US Atlas topology, with styling provided by Poppins font and custom CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/54aa58a446c940829a65b8e2fb984080?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
