{"version":"1.0","type":"rich","title":"Largest Cities by population in 2020","description":"This visualization displays the largest U.S. cities by 2020 population as scaled circles overlaid on a map of state boundaries. The map uses the `geoAlbers` projection and `geoPath` to render the states, while circle radii are determined by a `scaleSqrt` function based on population values. City coordinates are projected from latitude and longitude using the same projection. The example is built with React and D3 v5, sourcing city data from a CSV file with population and coordinates, and state boundaries from the us-atlas TopoJSON dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/caf7d740b7334465afad5d36529ca365?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
