This visualization displays the global spread of COVID-19 deaths, with a logarithmic y-axis showing smoothed daily death counts for each country over time. Hovering over a curve highlights the active country and displays a tooltip with its total deaths. The implementation uses React with d3.scaleTime, d3.scaleLog, and d3.line to render SVG paths. A d3.Delaunay triangulation and d3.voronoi overlay capture mouse events across the chart, while data is loaded from the CSSEGISandData COVID-19 time-series CSV.
