This interactive choropleth map displays the worldwide incidence of COVID-19 cases and deaths over time. Users can hover over countries for tooltip details or click to isolate a country, while moving the mouse below the map scrubs through dates from January to May 2020. The visualization uses D3 v5 with `d3.geoNaturalEarth` projections and `d3.geoPath` for rendering the SVG map, with a log-scale color encoding for case counts and a line graph for temporal trends. Data is loaded from external GeoJSON and JSON files.
