{"version":"1.0","type":"rich","title":"A9-US Choropleth Map","description":"This animated choropleth map displays the 2020 census population for each U.S. state, using a color scale to encode population values with interactive tooltips. The visualization loads population data from a CSV file and U.S. state boundaries from TopoJSON, then uses `d3.geoAlbersUsa()` for the projection and `d3.geoPath()` to render the SVG paths. State polygons are colored by population via a color scale, with a tooltip showing details on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/15ca91302a7b45db8f35addf11f37e09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
