We use the same logic to create a chart for next two variables: forks and size.

x = df['watchers'] 
y = df['forks'] 
ax.set(title='Deep Learning and Open Source Technologies', xlabel='Number of watchers', ylabel='Number of forks') 

Again, there's no correlation between forks and watchers in the case of deep learning and open source. Certain open source repositories have high number of watchers compared to deep learning.
