This choropleth map shows the population of each U.S. state using 2020 Census data, with states colored according to their population totals and a tooltip revealing the state name on hover. The visualization loads US states from the us-atlas TopoJSON file and renders them using d3.geoPath with the d3.geoAlbersUsa projection. Population values are mapped to a color scale, while the SVG states respond to mouse events for interactive inspection.
