A line chart tracks global cumulative COVID-19 deaths over time, using a logarithmic y-axis to show growth across multiple orders of magnitude. Built with React and D3 v6, it fetches live data from the Johns Hopkins CSSE GitHub repository via `d3.csv`. The chart renders as SVG, with scales created by `scaleTime` and `scaleLog`, axes via `axisBottom` and `axisLeft`, and a tomato-colored `MarkerY` annotation highlighting the 10,000-death threshold.
