The map displays all U.S. states as colored SVG paths, with each state assigned a distinct color from a categorical scale and a hover effect that turns it black. It uses d3.geoPath with the geoAlbersUsa projection to render state boundaries from TopoJSON data loaded via the us-atlas and geo-albers-usa-territories libraries. State names appear as tooltips through appended title elements, and the color scale is d3.scaleOrdinal with schemeCategory10.
