This choropleth map displays poverty rates across U.S. counties, with each county filled using a green sequential color scale from d3.scaleThreshold and d3.schemeGreens[5]. The visualization loads county boundaries from a TopoJSON file and joins them with CSV poverty data via d3.map, rendering the geographic features as SVG paths using d3.geoPath. A legend with a linear scale and axisBottom shows the poverty percentage range, while state borders are drawn as white strokes using topojson.mesh. Tooltips provide exact poverty percentages on hover.
