This visualization displays the global coronavirus death rate over time for multiple countries, with each line representing a country’s cumulative deaths on a logarithmic scale. A Voronoi overlay enables interactive hover detection, highlighting the nearest data point and displaying the country name, death count, and date. The chart uses d3.scaleTime, d3.scaleLog, and d3.line for rendering, with React managing state and SVG for output. Data is sourced from the Johns Hopkins COVID-19 dataset, processed to calculate mortality rates from death, confirmed case, and recovery time series.
