This chart visualizes global COVID-19 death totals over time using a line path, with a horizontal marker at the 1 million death threshold and a vertical marker at the most recent date. The React component uses D3 scales (scaleTime, scaleLinear) and a line generator to map the Johns Hopkins dataset, while custom XAxis and marker components render grid lines and labels. SVG output displays the path with a bold black stroke, styled tick marks, and formatted date labels.
