Forked from Let's make an interactive US Map with D3.js!
A county population bubble map for the US uses an SVG projection with geoAlbersUsa and d3.geoPath to render state and county boundaries from TopoJSON data. Circles positioned via pathGenerator.centroid are sized by a d3.scaleSqrt mapping COVID-19 case counts from a CSV dataset, with zoom enabled through d3.zoom for interactive exploration.
