This line chart displays annual US auto sales from 2005 to 2022, with the x-axis mapping years and the y-axis mapping sales figures. The visualization uses d3.scaleTime and d3.scaleLinear for axes, with d3.axisBottom and d3.axisLeft rendering ticks and labels. A red d3.line generator draws the sales trend path in SVG. Data loads from a CSV file via d3.csv, with year values parsed as dates. Axis labels and a title appear as SVG text elements, styled through the page’s stylesheet.
