GNU cflow. A sample flowchart.

The following flowchart shows call tree in GNU cflow.
Recursive calls are marked with (R). Clicking on this marker will bring you to the call that caused recursion. Such calls are marked with text (recursive, see LINE). Again, clicking on this marker will bring you back to the recursion root call.
A marker [see LINE] indicates that the expansion of the current node is available on line LINE. These markers are clickable as well.
Enjoy!
