This chart displays the cumulative global COVID-19 death toll over time, using a logarithmic scale on the y-axis to reveal the exponential growth pattern. The React component fetches time-series data from the Johns Hopkins CSSE GitHub repository and renders an SVG line chart. The code uses D3 v6 scales (`scaleTime`, `scaleLog`) and axes (`axisBottom`, `axisLeft`), with the line generated via `line()`. Gridlines extend across the plot, and the chart fills the browser window, updating as new data arrives.
