This line chart displays COVID-19 confirmed cases across China’s provinces, using province names as the x-axis and confirmed case counts as the y-axis. It is built with D3 v5, leveraging `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis` for smooth interpolation. The SVG renders gridlines, axis labels, and a maroon path with circles not included. Data comes from a local CSV file, and the visualization is produced via `d3.csv` loading and rendering into an SVG container.
