This line chart displays cumulative COVID-19 deaths over time for each country, using a log-scaled y-axis to accommodate wide value ranges. Each country’s time series is rendered as a black SVG path, generated with d3.line, while d3.scaleTime and d3.scaleLog map dates and death totals. The chart is built with React and D3 v5, with axes drawn via d3.axisBottom and d3.axisLeft, using data from the Johns Hopkins Coronavirus dataset.
