title: Does Seaborn's sns.load_dataset() function use real data?
body: <p>I know all of the datasets that can be loaded with sns.load_dataset() are all example datasets, used for Seaborn's documentation, but do these example datasets use actual data?</p>
  
  <p>I'm asking because I want to know if it's useful to pay attention to the results I get as I play around with these datasets, or if I should just see them as solely a means to learning the module.</p>
