This chart visualizes cumulative COVID-19 deaths over time for multiple countries, with each country's trajectory drawn as a gray line on a logarithmic y-axis. A red Voronoi overlay, generated using `d3-delaunay`'s `Delaunay` class, highlights proximity between data points for potential hover interactions. The visualization uses React, with D3 v5 for scales (time and log), axes, and line generation, and renders to SVG. Data comes from the Johns Hopkins COVID-19 time-series dataset, with the x-axis formatted monthly and y-axis using compact notation.
