This line chart displays car sales prices in the USA from 2009 to 2018, with the year on the x-axis and sales price on the y-axis. The visualization uses D3 v5 with SVG rendering, employing `d3.scaleTime` for the temporal axis and `d3.scaleLinear` for price values. A `d3.line` generator creates the purple path, while `d3.axisBottom` and `d3.axisLeft` produce labeled axes with gridlines. Data comes from a remote CSV file loaded via `d3.csv`, then parsed into Date and numeric values.
