A line chart tracks global cumulative COVID-19 deaths over time using a logarithmic scale for the y-axis, with rotated date labels on the x-axis. The visualization uses React and d3.v6, with `scaleTime` and `scaleLog` for axes and a `line` generator for the path. Data comes from the Johns Hopkins Coronavirus Dataset, loaded via `csv` into a React hook, and rendered as SVG with custom axes using `axisBottom` and `axisLeft`.
