## Instruction

Always add a title to your chart. This ensures that everyone, no matter if they know the data or not, understands what is presented on your chart. We've already discussed what makes a good title when we looked at the scatter plot; the same applies here.

To add this information to the chart, use the following command:

+labs(title="your_title", subtitle="your-subtitle", caption="your source")

Obviously, you'll add your own title, subtitle, and source info where the placeholder texts are. Don't forget the double quotes!

## Exercise

Add a title, a subtitle, and data source information to your chart. Follow the syntax used above.

A sample title might be "Wealthy means drunk?". A sample subtitle might be: "Relationship between the wealth of country and its alcohol consumption". The source information is: "Source: WHO and World Bank, 2010"

### Stuck? Here's a hint!

You should write:

labs(
title = "Does Wealthy Equal Drunk?",
subtitle = "The relationship between a country's wealth and its alcohol consumption",
caption = "Source: WHO and World Bank, 2010")
