A line chart displays global coronavirus death totals over time for multiple countries, with each country shown as a gray line. Hovering over the plot reveals a highlighted black path for the selected country. The visualization uses d3.scaleTime and d3.scaleLog for axes, d3.line for path generation, and a d3.Delaunay-based Voronoi overlay with transparent cells to capture mouse events and trigger country highlighting. Data comes from the CSSEGISandData COVID-19 time series CSV, rendered as SVG with React.
