2. Distorting the visuals.

3. Distorting the size of a bar.

Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?

Explain: I think I choose the line graph because it was selling more in the canteen every month.

Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.
