This line chart visualizes annual US automotive sales from 2005 to 2022, using a red path to show the sales trend over time. The visualization loads CSV data from a GitHub gist and renders it as an SVG using d3.scaleTime and d3.scaleLinear for the axes, with d3.axisBottom and d3.axisLeft providing tick marks. The chart includes labeled axes, gridlines, and a title, with data parsed to convert Year into Date objects and Sales into numbers.
