Thanks for the answer! It sounds like you're taking a bottom-up approach when reading code. Do you think we can use software to build this dependency graph and make it easier to read code?
Yes, technically it is possible. Some languages (and build tools) are a lot easier than others.
For purposes of learning the code, it may not be worth automating the dependency graph. You will probably learn more from tracking it down than you would if it was pre-generated for you.
