This example displays global coronavirus deaths over time as a multi-line chart, with each line representing a country’s cumulative death toll on a logarithmic scale. The visualization uses D3 v6 for scales, axes, and line generation, and renders the paths as SVG via React components. Data comes from the Johns Hopkins COVID-19 dataset, and the axis components are built with D3’s `axisBottom` and `axisLeft`, including rotated tick labels and grid lines.
