This fork displays Canadian COVID-19 vaccination counts over time using four smoothed lines for total vaccinations, people vaccinated, fully vaccinated, and boosters. It loads data from the Our World in Data GitHub repository via d3.csv, then renders the chart with d3.scaleTime, d3.scaleLinear, and d3.line with curveMonotoneX. A d3.bisector-based tooltip, gradient background, legend, and axis labels complement the React-managed SVG.
