A salesperson made a bar graph of different brands of cars sold in a month.

The bar graph shows the number of cars sold for each brand, with the following data:

- Toyota: 150 cars
- Ford: 100 cars
- Honda: 80 cars
- Chevrolet: 70 cars
- Nissan: 60 cars

This bar graph can help the salesperson visually understand the sales performance of each brand in comparison to one another. It can also help identify trends and patterns in the sales data.
