There are a number of different Python libraries with varying support for Excel and its many features. In this recipe, we use the xlsxwriter module to create a table and graph of the data. This module can be used for much more than that. This module can be installed by pip using the following command:
pip install xlsxwriter==0.9.9

We also use a custom utilcsv module that we wrote based on the previous recipe to handle interactions with CSVs. All other libraries used in this script are present in Python's standard library.
