This choropleth map visualizes poverty estimates across US states, with darker shades of gray indicating higher poverty rates on a 5-class ColorBrewer scale. The visualization merges data from a cleaned CSV file with US state GeoJSON boundaries using d3.csv and d3.json, then renders the map as SVG paths with d3.geoAlbersUsa projection and d3.geoPath. A d3.scaleQuantize maps poverty values to the color range, while states without matching data appear in light gray. The map includes a title and uses d3.v4 within a React framework.
