This choropleth map displays U.S. states rendered as sky-blue land masses with green internal borders, using an Albers USA projection that includes territories. The visualization loads geographic data from a TopoJSON URL and processes it with `topojson.feature` and `topojson.mesh`, then draws the paths using `d3.geoPath`. Built with React, the app fetches data asynchronously in a custom `useData` hook and conditionally renders the SVG after loading completes, leveraging d3.v5 for geographic calculations.
