This visualization displays car sales data over time as a line chart, with years on the x-axis and sales figures on the y-axis. It uses D3 v5 to load CSV data, parse dates with d3.timeParse, and render scales and axes via scaleTime, scaleLinear, axisBottom, and axisLeft. The line is drawn using the d3.line generator, with the SVG path styled in orange. The chart includes labeled axes and uses margins to position the plot within the SVG canvas.
