This example shows a line chart tracking total car sales per year from 2013 to 2021, with time on the x-axis and sales on the y-axis. Using D3 v5, it loads CSV data from a GitHub gist and parses dates with `d3.timeParse`. The chart employs `scaleTime` and `scaleLinear` for axes, while `d3.line` generates the red path. Grid lines are drawn via `axisBottom` and `axisLeft` with tick sizes spanning the plot area, and axis labels rotate for the y-axis.
