This visualization pairs a Natural Earth world basemap with a choropleth of U.S. agricultural exports from 2011. The world map uses `d3.geoNaturalEarth1` and `d3.geoPath` with TopoJSON data from world-atlas@2 to render country boundaries and graticules. The U.S. map employs `d3.geoAlbersUsa` to show state-level export values, with an interactive tooltip for additional detail. Both maps are drawn as SVG elements using D3 v7.
