This visualization tracks cumulative COVID-19 deaths over time for each country, using a logarithmic y-axis to accommodate the wide range of values. The React-based chart employs D3 v5 scales and generators, with `scaleTime` for dates and `scaleLog` for death counts, rendering individual country trajectories as colored SVG paths. Data comes from the Johns Hopkins Coronavirus dataset, loaded via `d3.csv` and transformed into per-country timeseries arrays. The chart includes axis components built with `d3.axisBottom` and `d3.axisLeft`, with a gridline effect from tick sizing.
