A multi-line chart displays cumulative coronavirus deaths over time for Canada’s provinces, with each province represented by a gray line. A log-scaled y-axis and time-scaled x-axis frame the data. Hovering over any point activates a Voronoi overlay, built with d3.Delaunay, which highlights the nearest province’s line and shows a tooltip with the death count and date. Data comes from the Johns Hopkins Coronavirus dataset, rendered as SVG via React and D3 v5.
