The question of how concepts and algorithms are represented is interesting. While this is a neat project, a lot of people including myself might say that a "visual" representation of code is actually more confusing. Perhaps it's because textual representations are 1-dimensional i.e. the representation of code as text can only grow in one direction. This makes it inherently simple in some sense.
I have found in my time teaching people about deep learning that proper visualizations of algorithms can help people grok things better[0]. Granted backprop and neural networks are really simple one dimensional algorithms.
