This chart displays cumulative global COVID-19 deaths over time from the Johns Hopkins dataset, using a logarithmic y-axis to accommodate the wide range of values. Lines and text labels mark significant milestones like the 1M death threshold. Built with React and D3 v6, it uses `scaleTime`, `scaleLog`, and `line` generators to render an SVG path, with custom `XAxis` and `YAxis` components that call `axisBottom` and `axisLeft` to draw grid lines and tick labels.
