This area chart displays car sales from 2001 to 2010, with time on the x-axis and sales count on the y-axis. The visualization uses D3 v5’s `area()` generator with a basis curve to create a smooth filled region, while `scaleTime` and `scaleLinear` map the data. Axes are rendered via `axisBottom` and `axisLeft`, and the data is loaded as CSV from a GitHub gist. The SVG output includes labeled axes and a title, with gridlines generated through tick sizes.
