A first cut at the full analytical interface. Colour every county by any variable (choose the classification — natural breaks, quantiles, equal interval, manual), then add filters on any other variables to isolate the subset you care about. Elections (2020) + Census/CVAP composition today; more sources and vintages as they land. Aggregate facts about places — no individuals.
Elections: RDH precinct returns aggregated to county, 2020 presidential. Population/CVAP: U.S. Census (ACS estimate + CVAP special tabulation). Classification runs on the filtered subset. This is a comparison of places, not a claim about individuals.
