This line chart displays US auto sales from 2005 to 2022, with years on the x-axis and sales figures on the y-axis. Using D3 v5, the code loads CSV data from a GitHub gist, parses the Year and Sales fields, and renders an SVG with d3.scaleTime, d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.line. Axes include tick marks, labels, and a title. The line path appears in red with a 4-pixel stroke, while grid lines and a rotated y-axis label enhance readability.
