Clustered heatmaps

Heatmaps are extremely useful to visualize a correlation matrix, but clustermaps are better. A Clustermap allows to uncover structure in a correlation matrix by producing a hierarchically-clustered heatmap:

df_corr = df.corr()

fig = sns.clustermap(df_corr)
plt.setp(fig.ax_heatmap.xaxis.get_majorticklabels(), rotation=90)
plt.setp(fig.ax_heatmap.yaxis.get_majorticklabels(), rotation=0)

To prevent overlapping of axis labels, you can reference the Axes from the underlying fig object and specify the rotation. You can learn about the arguments to the clustermap() function here.
