This visualization displays the cumulative global COVID-19 death toll over time, with each country represented as a line on a logarithmic scale. A Voronoi overlay, generated using `d3.Delaunay` and the `voronoi()` method, creates clickable regions around plotted points to enhance interaction. The chart is built with React and renders paths and axes using D3 v5’s `line()`, `scaleTime()`, and `scaleLog()` functions. Data is sourced from the Johns Hopkins Coronavirus Dataset, loaded via D3’s `csv()` and parsed with `timeParse()`.
