This example shows cumulative COVID-19 deaths over time as a single black line chart, with a logarithmic y-axis for deaths and a time-based x-axis formatted by month/year. The data comes from the CSSE COVID-19 time series CSV. Built with React and D3 v6, it uses `scaleTime`, `scaleLog`, and `line` generators, while `axisBottom` and `axisLeft` render labeled gridlines. The SVG includes axis titles and optional teal marker lines for highlighting specific values.
