A multi-line chart displays global cumulative coronavirus deaths over time, with each line representing a country. The chart uses a logarithmic y-axis to accommodate wide variations in death tolls and includes gridlines for readability. The data comes from the Johns Hopkins Coronavirus Dataset. Built with React and D3 v5, the visualization uses `d3.csv`, `scaleTime`, `scaleLog`, and `d3.line` to generate SVG paths, with axes created via `axisBottom` and `axisLeft`.
