This chart shows cumulative COVID-19 deaths over time for each country, plotted on a log-scaled y-axis. Hovering over any point highlights that country’s full line and displays a tooltip with the exact death count and date. The visualization uses React with D3 v5 scales (`scaleTime`, `scaleLog`) and line generators, while `d3.Delaunay` from `d3-delaunay` builds a Voronoi overlay to capture mouse events, making it easy to select nearby data points. Data comes from the Johns Hopkins Coronavirus dataset via CSV.
