{"version":"1.0","type":"rich","title":"Us 2020 elections by county","description":"A choropleth map of the US 2020 presidential election results by county colors each county on a red-blue diverging scale based on the margin between Democratic and Republican votes, with state borders overlaid in white. Hovering over a county updates a detail panel showing the vote percentages and a horizontal bar comparison between Joe Biden and Donald Trump. The visualization uses D3 v4 with `d3.geoAlbersUsa` and `d3.geoPath` to render TopoJSON county boundaries from the US Census, while `d3.scaleSequential` with `d3.interpolateRdBu` handles the color encoding. Data comes from The Guardian and USA Today.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fd70d0374994489d852adcf9d2e309fe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
