This fork of T1-MAP-CM uses two linked maps to compare a neutral world basemap with a US agricultural exports choropleth. The world map, rendered via `d3.geoPath` and the Natural Earth projection `d3.geoNaturalEarth1`, shows only country boundaries as a basemap. The US map, projected with `d3.geoAlbersUsa`, colors states by 2011 export totals from the Plotly CSV `2011_us_ag_exports.csv`. Both maps use TopoJSON sources, and a custom tooltip appears on hover.
