This bar graph visualizes car sales data for ten vehicle types, showing the number of units sold in 2021. The chart uses a vertical bar for each car type, with the height corresponding to its sales figure. The visualization is built with D3 v7, using `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the numeric y-axis, and SVG rectangles for the bars. Data is loaded from a remote CSV file via `d3.csv` and rendered with axis labels for "Car Types" and "Sales".
