The chart displays cumulative COVID-19 deaths over time for each country, with a logarithmic y-axis to accommodate wide value ranges. Data comes from the Johns Hopkins COVID-19 dataset and is rendered as SVG paths using d3.line, d3.scaleTime, and d3.scaleLog within a React component. Each country’s time series is drawn with a randomly assigned stroke color, while axes are generated with d3.axisBottom and d3.axisLeft. The visualization also includes axis labels and gridlines, with raw data processed via Promise.all and csv parsing.
