This example visualizes global coronavirus deaths over time for each country, using a log-scaled y-axis to accommodate the wide range of values across nations. A Voronoi overlay, generated via `d3.Delaunay`, maps the nearest data points to enable smooth hover interactions that highlight the selected country’s line. The chart is built with React and D3 v7, rendering SVG paths for the time series and axes, with data sourced from the CSSE COVID-19 global time series dataset.
