A fork of a line chart displays cumulative COVID-19 deaths over time for each country on a log scale. Semi-transparent red Voronoi cells, generated by `d3.Delaunay` from a sparse set of points, overlay the chart to illustrate a hover-interaction technique, though the hover handler only logs to the console. Built with React and D3 v5, the SVG visualization renders axes, grid lines, and multiple country paths from the Johns Hopkins dataset.
