{"version":"1.0","type":"rich","title":"USA 2012 presidential election bar symbols (d3v3)","description":"This block visualizes the 2012 U.S. presidential election results at the county level using D3v3. Each county is represented by a vertical bar symbol, with bar height encoding the margin of victory and color indicating the winning candidate (blue for Obama, red for Romney). The visualization uses a TopoJSON file (`elpo12p010g.topojson`) containing county-level vote data, including vote counts and percentages. Built with Blockbuilder.org, this example is forked from almccon's earlier election visualization blocks. The map displays all U.S. counties as proportional bar symbols, with the topojson geometry defining county boundaries and the attached properties driving the bar heights and colors.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-243e4a79de9257980fe1a0e4bc618dfc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
