A multi-line chart compares cumulative COVID-19 deaths across countries over time, using a log-scaled y-axis to reveal relative growth patterns. The visualization reads data from the Johns Hopkins Coronavirus Dataset and renders with React and D3 v5, using `scaleLog`, `scaleTime`, and `line` for the chart. An interactive Voronoi overlay, built with `Delaunay.voronoi`, enables hover-triggered tooltips that display each country’s death count and date.
