This example shows the global cumulative death toll from COVID-19 over time as a single line chart with a logarithmic y-axis. It loads live data from the Johns Hopkins Coronavirus dataset via `d3.csv` and computes daily totals by summing country values. The chart is built with React and D3 v5, using `scaleTime` and `scaleLog` for axes, while `line` generates the path. SVG rendering with axis labels and gridlines is used, and the chart updates automatically when new data is fetched.
