I'm looking for a piece of software where I can basically draw branches, almost in a tree structure and have headings and text for each node.
While stepping through legacy code I often find myself debugging functions that call other functions, that call other functions.
It can get fairly complex, and I would like to draw up some "visual map", not to be confused with a UML or flow chart. No graphics per say, mostly text, but in tree form.
I know Excel would work, paper and pen too, but I am curious if there is software like this, possibly even a visual studio plugin?
