A line chart displays cumulative global COVID-19 deaths over time, using a logarithmic y-axis and a time-based x-axis. Built with React and D3 v5, it renders an SVG path via `d3.line` and `d3.scaleLog`, with axes created by `d3.axisBottom` and `d3.axisLeft`. The data comes from the CSSEGISandData COVID-19 time series CSV.
