This chart visualizes total car sales from 2013 to 2022 as a smooth sky-blue area curve. It uses d3.scaleTime and d3.scaleLinear for the axes, with d3.area and d3.curveBasis to generate the filled path. The sales data is loaded from a remote CSV file, and d3.axisLeft and d3.axisBottom render the labeled axes with gridlines. The title and axis labels are added as SVG text elements.
