Multi-country cumulative coronavirus death tolls are plotted over time as colored lines on a logarithmic scale, using a React component that renders SVG paths. The chart pulls data from the Johns Hopkins COVID-19 dataset via `d3.csv`, transforms it with `timeParse`, and draws axes using `d3.axisBottom` and `d3.axisLeft`. Line generation relies on `d3.line`, while `d3.scaleLog` and `d3.scaleTime` handle value mapping. Each country gets a randomly assigned stroke color.
