This line chart visualizes US auto sales from 2005 to 2022, plotting airline prices over time. The data is loaded from a CSV file using d3.csv, then rendered as an SVG path generated by d3.line. It uses d3.scaleTime and d3.scaleLinear to map the x and y dimensions, with axes created via d3.axisBottom and d3.axisLeft. The chart includes labeled axes and a title, with gridlines drawn through tick size extensions. The line path is styled with a red stroke.
