This example displays a smooth, curved area chart showing yearly car sales over time. It uses D3.js v5 APIs including `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to render the path in an SVG. The data is loaded from a CSV file via `csv` from D3, with years parsed as dates. Axes, labels, and a title are generated using `axisLeft` and `axisBottom`, and the chart is styled with magenta fill.
