This line chart visualizes global COVID-19 death totals over time, using a time-series dataset from the CSSE at Johns Hopkins. It plots a single black path generated with d3.line, with axes built via d3.axisBottom and scaleTime/scaleLinear. React manages the SVG rendering, while d3-selection updates the axis. Two marker lines highlight the current date and the six-million-death threshold, styled with CSS classes in the accompanying stylesheet.
