This chart tracks cumulative COVID-19 mortality over time for each country, with each line representing a nation’s reported death toll. It uses a logarithmic y-axis to accommodate the wide range of counts, and a time-based x-axis spanning the pandemic’s progression. The visualization is built with React and D3 v5, utilizing `scaleTime` and `scaleLog` for scaling, `line` for path generation, and `axisBottom`/`axisLeft` for grid axes, rendered as SVG paths. Data is fetched from the Johns Hopkins CSSE COVID-19 global time-series CSV, aggregated by country.
