This example displays a line chart of global cumulative COVID-19 deaths over time, using a logarithmic y-axis to accommodate the data’s exponential growth. The visualization is built with React and D3 v5, rendering an SVG path generated by `d3.line`, with axes created via `d3.axisBottom` and `d3.axisLeft`. Data is loaded from the Johns Hopkins CSSE time-series CSV using `d3.csv`, and dates are parsed with `d3.timeParse`. The chart includes gridlines, axis labels, and a headline, with styling applied through CSS.
