Using D3 v5 within a React component, this chart visualizes global cumulative COVID-19 deaths over time from the JHU CSSE dataset. A single SVG line path traces the rising death totals, with gridlines and labeled axes generated by `d3.axisBottom` and `d3.axisLeft`. The code scales dates with `d3.scaleTime` and death counts with `d3.scaleLinear`, fetching data via `d3.csv` and formatting it with custom parsing and reduction logic.
