Visualise the Dataset

Visualising the data is an important step of the data analysis. With a graphical visualisation of the data we have a better understanding of the various features values distribution: for example we can understand what’s the average age of the people or the average BMI etc…We could of course limit our inspection to the table visualisation, but we could miss important things that may affect our model precision.

import matplotlib.pyplot as plt
dataset.hist(bins=50, figsize=(20, 15))
plt.show()
