{"version":"1.0","type":"rich","title":"Map Visualization of COVID-19 Cases in the U.S.","description":"This map visualizes confirmed COVID-19 cases across U.S. states, using a color scale to indicate case counts. Hovering reveals a state's name, while clicking toggles the display of case numbers on the map. Built with D3 v4, the visualization uses `d3.geoAlbersUsa` and `d3.geoPath` to render state boundaries from GeoJSON data. Case data comes from state health agencies and the CDC, as aggregated by the New York Times, and loads via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6aa17be484af4422b90a74084d0d6650?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
