This visualization displays cumulative COVID-19 deaths over time using a standard linear y-axis, drawn as an SVG path. It loads global death data from the Johns Hopkins CSSE time-series dataset via `d3.csv` and parses dates with `d3.timeParse`. The chart uses `d3.scaleTime` and `d3.scaleLinear` for its axes, with gridlines generated by `d3.axisBottom` and `d3.axisLeft`. React manages the component structure, while D3 v7 handles the line generation with `d3.line` and scales.
