This line graph displays total car sales from 2013 to 2021, with the timeline on the x-axis and sales amounts on the y-axis. Using d3.csv to load external data, the visualization parses date strings with d3.timeParse and scales them via d3.scaleTime and d3.scaleLinear. The chart renders as an SVG path generated by d3.line, with axis labels and gridlines created through d3.axisBottom and d3.axisLeft. The line is styled with a red stroke, and axis ticks include padded labels.
