This chart shows the global progression of COVID-19 deaths over time, with each country represented by a line on a logarithmic scale. A Voronoi overlay enables interactive highlighting: hovering near any data point activates and emphasizes the corresponding country’s full trajectory. The visualization is built with React and D3 v5, using `d3.Delaunay` and `d3.voronoi` for the hover detection, and renders as SVG with data from the CSSE COVID-19 time series dataset.
