A line chart tracks global cumulative COVID-19 deaths over time using a logarithmic y-axis scale, making early exponential growth readable alongside later plateaus. The visualization uses React with D3 v5, including `scaleLog`, `scaleTime`, and `line` with `curveNatural`. The chart renders as SVG with grid lines, dashed markers at 10,000 deaths and the final date, and tooltips via `<title>` on zero-radius circles. Data comes from the CSSE COVID-19 time-series CSV, summed across all countries.
