This chart shows cumulative COVID-19 deaths over time for each country, using a log-scaled y-axis to accommodate wide variation. Hovering any point triggers a Voronoi overlay via `d3.Delaunay` to highlight the corresponding country’s line and display a tooltip with the date and death count. Data comes from the Johns Hopkins CSSE GitHub repository, and the visualization is built with React and D3 v5, using SVG paths for lines and axes.
