This choropleth map displays confirmed COVID-19 cases across Argentine departments, using a logarithmic color scale from blue to red to represent case counts. The visualization renders geographic boundaries as SVG paths via d3.geoPath with a Transverse Mercator projection, and features zoom and pan controls via d3.zoom. Hovering a department triggers a CSS pink highlight and reveals a tooltip with the department name, province, and case total. The map reads TopoJSON data from a GitHub-hosted United Kingdom counties file, with the fork repurposing that geometry for Argentina.
