This choropleth map displays the estimated poverty rate for each US county in 2021, using a blue color scale to show the percentage of the population in poverty. The map is rendered as an SVG using d3.geoPath and topojson features, with state boundaries outlined in white. A legend and title are included, and the data, sourced from the USDA, is loaded from a CSV file and joined to the map using county IDs. The visualization uses D3 v5 and the topojson library for geographic data processing.
