A Call-Graph is a visual representation of calls between functions/procedures/methods etc. Typically created from the entry point of the code through each of the calls.
A Call-Graph is a useful tool in researching problems in your code. By seeing a visual reference of the order calls are performed, it allows the individual to trace back to a piece of code quicker. This allows them to test data output in various points faster by reducing the number of files that will have to be opened and searched to track this data manually.
