The chart plots cumulative coronavirus deaths over time as a black line on a linear y-axis, with gridlines and labeled axes. It uses React components to render an SVG, while D3's `scaleTime`, `scaleLinear`, and `line` generator handle scales and the path. Data comes from the Johns Hopkins CSSE time-series CSV, aggregated by summing daily death totals. The visualization includes fixed marker lines at 10,000 deaths and the final date.
