This chart visualizes daily COVID-19 death totals over time, derived from the Johns Hopkins CSSE time-series dataset. The line chart plots dates on the x-axis against cumulative global deaths on the y-axis. The code uses React to manage the component lifecycle, with `useData` fetching the CSV via `d3.csv` and transforming it using `timeParse` and array methods. The rendered line is drawn as an SVG path within a React-based `LineChart` component.
