The idea

Why draw pictures?

Your class file Data for Bakery Shop.xlsx has 1,095 rows: three years of daily sales of cakes, pies, cookies, smoothies and coffee.

Nobody can see a pattern by reading 1,095 rows. But the right picture shows it in two seconds. That's data visualisation.

Use a table when someone needs exact numbers. Use a chart when the point is a pattern.
