It should be assumed that at the beginning of each recipe, pandas, NumPy, and matplotlib are imported into the namespace. For plots to be embedded directly within the notebook, you must also run the magic command %matplotlib inline. Also, all data is stored in the data directory and is most commonly stored as a CSV file, which can be read directly with the read_csv function.
>>> import pandas as pd
>>> import numpy as np
>>> import matplotlib.pyplot as plt
>>> %matplotlib inline
>>> my_dataframe = pd.read_csv('data/dataset_name.csv')
