I still support a full stack web app that I wrote for a client 10 years ago. Whenever I revisit a section of code that I haven't looked at since then, I always have to re-learn the code's logical structure and function. I'm sure most developers have experienced this. I wonder if, 10 years ago, I were to have routinely viewed my code in a visual manner like in the article, would today's relearning process take less time and frustration. Sort of like when you revisit an old beloved vacation spot. Even though those memories have aged, the layout of the spot is relatively the same. You quickly remember where things are located. I also wonder what value a code visualization like this would have for a new developer working with the code.
