This chart tracks cumulative COVID-19 deaths by country over time on a logarithmic scale, using data from the Johns Hopkins Coronavirus Dataset. Each grey line represents a country’s death trajectory, and hovering over a data point via a Voronoi overlay highlights the corresponding country’s full series in black while displaying a tooltip with the exact date and death count. The visualization is built with React and D3 v5, employing `d3.scaleLog`, `d3.line`, and `d3.Delaunay` from the d3-delaunay library to enable smooth hover interactions across the SVG-rendered paths.
