This visualization displays global COVID-19 confirmed cases and deaths on a world map, using a spectral color scale to represent case counts per country. Built with React and rendered as SVG, it employs d3.geoNaturalEarth1 and d3.geoPath to project geographic boundaries from world-atlas TopoJSON, while loading case data from a TSV file. A custom color legend with circles and text labels clarifies the scale, and hovering over a country highlights it in red and shows a tooltip with its name, case count, and death toll. The map supports zooming through d3.zoom, and the color scale uses d3.scaleOrdinal with d3.schemeSpectral.
