This visualization displays global Covid-19 death totals over time as a smooth, logarithmic line chart, with tooltips on hovered points and dashed marker lines at 10,000 deaths and the latest date. It loads live time-series data from the CSSE at Johns Hopkins via `d3.csv`, aggregates daily global totals, and renders with React components using `d3.scaleTime`, `d3.scaleLog`, `d3.line` with `curveNatural`, and SVG axes from `d3.axisBottom` and `d3.axisLeft`. The chart updates responsively to the browser window size.
