A multi-line chart tracks cumulative COVID-19 deaths over time for each country, using a logarithmic y-axis to accommodate wide numeric ranges. Hovering over any point triggers a Voronoi overlay, powered by `d3.Delaunay`, to highlight the nearest country’s full trajectory and display a tooltip with its death count and date. The visualization is built with React and D3 v5, rendering SVG paths via `d3.line` and scales from `d3.scaleTime` and `d3.scaleLog`. Data comes from the Johns Hopkins Coronavirus dataset.
