A line chart displays annual US auto sales from 2005 to 2022, with a blue line tracing sales volume over time against labeled axes. Built with D3 v5, the visualization uses `scaleTime` and `scaleLinear` for axes, `axisLeft` and `axisBottom` for ticks, and `line()` to generate the path. Data is loaded from a CSV and rendered as SVG, with titles and axis labels styled via CSS. The chart emphasizes long-term sales trends.
