{"version":"1.0","type":"rich","title":"2020 presidential election margins (preliminary results)","description":"A map of the 2020 U.S. presidential election shows state-level vote margins as concentric rings overlaid on a geographic projection of state borders. The rings encode excess votes: the inner radius represents the losing party's votes, the outer radius the winner's, making large-population states with narrow margins appear as thin circles. Using D3 v5 with `d3.geoPath` and `d3.forceSimulation`, the visualization aggregates county-level results from the US_County_Level_Election_Results_08-20 dataset, and renders SVG elements with `d3.arc` to generate the ring geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c68421811aff4b588df4869426869108?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
