This visualization displays global COVID-19 case data on an interactive world map using a natural Earth projection, with each country rendered as a green SVG path that turns red on hover. The map uses d3.geoPath with d3.geoNaturalEarth1 for geographic projection, and d3.zoom enables panning and zooming. Country boundaries come from the world-atlas TopoJSON dataset, while country names are joined via the corresponding TSV file. The sphere background is styled blue, and the visualization relies on D3 v5 and topojson.feature to process the geographic data.
