This line chart displays annual U.S. auto sales by brand, with the x-axis mapping the year and the y-axis showing total sales volume. The visualization uses D3 v5's `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while the `line` generator draws the trend line. Data is loaded from a CSV file via `d3.csv`, and the chart is rendered as an SVG with styled gridlines and axis labels. The title "Sales of the item at the time" appears above the plot.
