This example shows a line chart of car sales from 2001 to 2010, with the year on the x-axis and sales figures on the y-axis. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `line`, `axisBottom`, and `axisLeft` APIs to render a maroon line and gridlines as SVG. Data is loaded from a CSV file using `csv()`, then parsed and plotted, with axis labels and a title included.
