This line chart shows the global cumulative death toll from COVID-19 over time, plotted as a single black line on a log-scale y-axis. The visualization uses React with D3 v5, employing `scaleTime` for the x-axis and `scaleLog` for the y-axis, with grid lines from `axisBottom` and `axisLeft`. Data comes from the Johns Hopkins Coronavirus dataset, processed via CSV parsing to aggregate daily death totals by summing across all countries.
