This interactive line chart displays cumulative coronavirus deaths by country over time, using a logarithmic scale to compare countries with vastly different death tolls. Hovering over the visualization triggers a Voronoi overlay, built with d3-delaunay, to identify the nearest data point and highlight its corresponding line with a tooltip. The chart is rendered with SVG within a React framework, using d3.scaleTime and d3.scaleLog for axes and d3.line for path generation. Data comes from the Johns Hopkins Coronavirus Dataset.
