This visualization displays global coronavirus death totals over time, with each country represented as a thin gray line on a logarithmic scale. A Voronoi overlay enables interactive country selection, highlighting the chosen line in black on hover. Built with React and D3 v5, the chart uses `d3.scaleLog`, `d3.scaleTime`, and `d3.line` to generate SVG paths. Data comes from the CSSEGISandData COVID-19 time series, fetched via `d3.csv`. The Voronoi diagram is constructed with `d3-delaunay` to map mouse position to the nearest data point.
