I honestly don't understand the point of this. Is it just a visualization of the directory structure? I expect code visualization to more or less ignore the file structure and focus on semantic analysis. For example, show the major components of the system and how they interact. Perhaps the major components are represented by some kind of a module, or a collection of modules. I don't have any concrete ideas. But I was expecting something in this vicinity.
