Exhaustive graph of subroutines

Hello

Does it exist a CPAN module that computes the exhaustive graph of the 
subroutines of a script ?

Example:

Suppose script.pl contains the following code :

sub routine_B2 { ... }

sub routine_B1 { ... }

sub routine_A2 { ... routine_B2(); ... }

sub routine_A1 { ... routine_B1(); ... }

routine_A1();
routine_A2();


The module would produce the following graph :

main::BEGIN
   routine_A1::BEGIN
      routine_B1::BEGIN
   routine_A2::BEGIN
      routine_B2::BEGIN
