This visualization shows cumulative COVID-19 deaths over time for each country, plotted on a logarithmic scale with a Voronoi overlay that highlights the nearest data point to the cursor, displaying the active country's name. Built with React and D3 v5, it uses `scaleTime` for the date axis, `scaleLog` for the death counts, `d3.line` for the polylines, and `d3.Delaunay` from the `d3-delaunay` package to compute the Voronoi cells for hover detection. Data comes from the Johns Hopkins CSSE GitHub repository.
