A line chart visualizes global cumulative COVID-19 deaths over time using a logarithmic y-axis. The chart loads daily global death totals from a Johns Hopkins University CSV dataset, parses the data with `d3.csv` and `timeParse`, and renders an SVG line using `d3.line`, `scaleTime`, and `scaleLog`. Red strokes mark the trend, with gridlines and labeled axes generated by `axisBottom` and `axisLeft`. The React component updates as new data becomes available.
