A fork of a line chart showing cumulative COVID-19 deaths over time for multiple countries, plotted with a logarithmic y-axis. Hovering over the chart highlights a country’s full time series in bold black, using a Voronoi overlay built with `d3.Delaunay` to capture mouse events on the densely overlapping lines. The visualization is rendered as SVG via React, with data sourced from the Johns Hopkins Coronavirus dataset, and uses `scaleLog`, `scaleTime`, and D3’s `line` generator to position and draw each country’s path.
