Extracting features for correlation
In this exercise, you'll work with a version of the salaries dataset containing a new column called "date_of_response".
The dataset has been read in as a pandas DataFrame, with "date_of_response" as a datetime data type.
Your task is to extract datetime attributes from this column and then create a heat map to visualize the correlation coefficients between variables.
Seaborn has been imported for you as sns, pandas as pd, and matplotlib.pyplot as plt.
