Seaborn allows you to make a correlogram or correlation matrix really easily. Correlogram is awesome for exploratory analysis: it makes you quickly observe the relationship between every variable of your matrix. It is easy to do it with seaborn: just call the pairplot() function!

# libraries
import seaborn as sns
import matplotlib.pyplot as plt

# load data set
df = sns.load_dataset('iris')

# Basic correlogram
sns.pairplot(df)
plt.show()
