There was an interesting chart I was looking at recently in the Washington Post:
The writer was talking about the difference in perception in the cost of living or "to thrive" in life between regular working Americans and economists. The line chart was pretty simple. It outlined the increase in male annual income, but it also showed the increases in the costs of college, healthcare, housing, and vehicle. Because the graph was color-coded, you can immediately see that the cost of healthcare increased much more than the other categories.
The writer used the data to provide context but was able to also show how much more people were paying for healthcare vs other categories. It was simple and easy to understand.
