Expected Behavior

The pandas documentation provides many examples and the expected output to make understanding their API easier. For example, see the Examples section on https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.merge.html.
Our docs should follow this pattern and provide many examples + expected output, especially in the Research Environment docs.
