This visualization tracks cumulative COVID-19 deaths by country over time using a log-scaled line chart. A Voronoi overlay, built with d3.Delaunay, enables smooth hovering to highlight the active country’s line and display a tooltip with the death count and date. The chart uses React with d3.v5 for scales and axes, rendering SVG paths from data sourced from the Johns Hopkins Coronavirus Dataset.
