'Diagram of the routines used in the execution of a Fortran code

I am trying to modify a complex Fortran code for fluid dynamics written by many people which consists of many routines, subroutines, and functions. I wonder if there is an option in gdb or any other debugger or code that can generate a diagram of the routines called when the code is executed with a specific option. I am looking to generate a diagram like this or similar where I can see all the routines and subroutines that were called when executing Fortran the code, so I can have an idea about what routines to modify. enter image description here

Rather than use a debugger it would probably be more common to use the output of a profiler - Is it possible to get a graphical representation of gprof results? provides a few suggestions, and below is the output generated by using gprof and gprof2dot on one of my own little codes
