Final Project
This interactive map displays confirmed COVID-19 deaths and cases by U.S. county, with each state labeled at its geographic centroid. The visualization projects TopoJSON boundary data using `d3.geoPath` and renders state shapes as SVG paths, colored steelblue with white borders and hover states that turn red. County-level CSV data is loaded via `d3.csv` and parsed, though the map currently presents only the state-level geometry rather than county-specific values. The implementation uses React without explicit components, importing utilities directly from D3 v4.
