A multi-line chart tracks cumulative COVID-19 deaths over time for each country, using a logarithmic y-axis to accommodate wide value ranges. The visualization loads data from a CSSEGISandData GitHub CSV and renders it as SVG paths via React. D3’s `scaleTime`, `scaleLog`, and `line` generator plot the series, while custom React components handle `axisBottom` and `axisLeft` with gridlines. Each country’s line receives a randomly generated RGB stroke color. The chart includes axis labels and a title, with tick formatting showing month/year and abbreviated large numbers.
