This chart tracks cumulative coronavirus deaths worldwide over time using a line graph with a linear y-axis. The data originates from the Johns Hopkins Coronavirus Dataset and is aggregated daily from the CSV via `d3.csv` and `timeParse`. The visualization is built with React and D3 v5, using `scaleTime`, `scaleLinear`, and `line` to render the SVG path, while `axisBottom` and `axisLeft` add gridlines and labeled axes.
