The CORONA Live chart displays the cumulative global death toll from COVID-19 over time as a single black line, with a horizontal marker at one million deaths and a vertical marker at the latest date. It renders as an SVG using React components and D3 v5 scales (`scaleTime`, `scaleLinear`) and a `line` generator. Data is loaded via `d3.csv` from the Johns Hopkins CSSE time-series dataset, aggregated daily by summing death counts across all countries.
