A line chart displays annual US auto sales from 2005 to 2022, with time on the x-axis and sales figures on the y-axis. The SVG rendering uses D3 v5 APIs including `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line`, with data loaded via `d3.csv` from a remote gist source. Red gridlines and labeled axes frame the single red line, which visualizes the full annual sales trend.
