This visualization tracks cumulative COVID-19 deaths over time for multiple countries, with each country represented as a colored line on a logarithmic scale. The chart uses React with D3 v5, employing `scaleTime` and `scaleLog` for axes and `d3.line` to generate SVG paths from the Johns Hopkins CSSE time-series data. Axis components utilize `axisBottom` and `axisLeft` with interactive tick formatting.
