Add annotations to help readers focus on your story.
Not everyone who looks at an un-annotated chart will see the same story. You can help your readers focus on the important part of the story by adding annotations.
We noticed at the beginning that Zimbabwe's alcohol consumption is still increasing. Readers may not see this at first, so let's add a notation about it. We will use the same syntax as in the previous exercise, but with different values:
geom_text(aes(label="text", x=position_x, y= position_y), size=3, color="grey")
Notice the new argument,
size. It determines the size of the text.
