{"version":"1.0","type":"rich","title":"USA 2016 presidential election","description":"This choropleth map shows the 2016 U.S. presidential election results by county, coloring each county by the percentage of votes received by the Republican candidate. It uses D3 v4 with `d3.geoAlbersUsa` for the projection and `d3.geoPath` to draw SVG paths from a TopoJSON file of U.S. counties. County-level vote data from a CSV is joined to the map via a lookup table keyed by FIPS codes, and a linear color scale maps vote percentages from blue through purple to red.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-12c384a392d68ac954d66cb4ecdd4a30?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
