This example displays the global cumulative death toll from COVID-19 over time as a single black line on a log-scaled y-axis, with labeled axes and a title. The chart uses React to render an SVG and relies on `d3.scaleTime`, `d3.scaleLog`, and `d3.line` for data mapping and path generation, while `d3.axisBottom` and `d3.axisLeft` create the gridlines. Data comes from the JHU CSSE COVID-19 time-series CSV, aggregated daily across all countries, with deaths counted from the start of the outbreak.
