This area chart shows car sales from 2001 to 2010, with the year on the x-axis and sales on the y-axis. The chart uses D3 v5 to load CSV data, apply time and linear scales, and render SVG axes with grid lines. An `area` generator with `curveBasis` creates a smoothed filled region below the sales line, styled in blue. The title and axis labels are added as SVG text elements.
