This line chart visualizes car sales figures from 2009 to 2019, plotting yearly totals on a blue line against a time-based x-axis and a linear y-axis. The chart uses a CSV data source loaded via D3’s `csv` function, with axes and labels rendered using `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`. The line path is generated with `line`, and the SVG output includes styled tick marks, red axis labels, and a title.
