The chart shows the global cumulative death toll from COVID-19 over time on a logarithmic y-axis, making the exponential growth visible as a straight line. A React component renders a single SVG path using `d3.line`, with `d3.scaleLog` and `d3.scaleTime` mapping the data, which is loaded from the CSSEGISandData GitHub repository. `d3.axisBottom` and `d3.axisLeft` provide gridlines, while commented-out marker lines suggest intended annotations for current date and the 10,000-death threshold.
