This area chart displays annual US automotive sales from 2005 to 2022, with dates on the x-axis and sales numbers on the y-axis. Using D3 v5, the code loads CSV data and renders an SVG with `d3.scaleTime` and `d3.scaleLinear` for scales, `d3.axisLeft` and `d3.axisBottom` for axes, and `d3.area` with `curveBasis` to generate the filled path. The chart includes labeled axes and a title, with data sourced from a GitHub gist.
