This chart shows car sales from 2008 to 2018 as a smooth area chart, with the line tracing sales over time and a pink fill beneath it. The visualization uses D3 v5’s `scaleTime` and `scaleLinear` for axes, `line` and `area` generators with `curveBasis` for smoothing, and `axisBottom`/`axisLeft` for tick marks. Data is loaded from a CSV URL, with years parsed via `d3.timeParse` and sales as numbers. The SVG is 930 by 450 pixels, with gridlines, axis labels, and a bold title.
