Smoothed Daily Coronavirus Deaths Line Chart
This chart plots smoothed daily coronavirus deaths over time for the top 50 countries by cumulative deaths, using a logarithmic y-axis to reveal relative trends across widely varying scales. The React app renders SVG lines with D3 scales and generators, while a D3-Delaunay Voronoi overlay enables hover interaction, highlighting the nearest data point and its corresponding country line with a tooltip. Data comes from the Johns Hopkins COVID-19 dataset, and daily values are smoothed via repeated averaging (15 iterations) before plotting.
