A log-scale line chart tracks cumulative COVID-19 deaths over time for countries, using data from the Johns Hopkins Coronavirus Dataset. Each country appears as a separate colored path, with the y-axis transformed by `scaleLog` and the x-axis by `scaleTime`. Built with React and D3 v5, it uses `d3.line`, `axisBottom`, and `axisLeft` to render the SVG, while grouping the CSV timeseries rows by country into individual line sequences.
