I do code review for legal cases on occasion. When I do, and when possible as sometimes the tools I can use are specified before I get the job, I like to use doxygen (https://www.doxygen.nl/ https://www.doxygen.nl/) to convert the code to html. It also creates call graphs. It is nice because it links to function and method definitions where it can, so as I go through the code I open each function I am teaching in a new tab - the open tab set simulates the call stack.
