How to draw the distribution, like Fig.3

[RaymondByc]

I want to check the improved representation of the trained model with GFL, so I want to draw the distribution of feature map like Fig.3.

What should I do？

By the way, I think the plot is just for visulization to make readers understand better. Am I right?
