The README looks somewhat encouraging.

This module was written by

    Jarkko Hietaniemi
    jhi@...

Jarkko has moved onto other things, so now I'm maintaining this distri
+bution.
I have no great plans for it, but will try to address any bugs reporte
+d,
and follow all modern conventions, etc. Pull requests and patches most
+ welcome :-)

Also, there is some more info in the Changes file:

Revision history for Perl module Graph
 
0.96_01 2014-03-09 @NEILB
    - Taken over maintenance from JHI
    - Specified min perl version 5.6.0
    - Tweaked COPYRIGHT and LICENSE in pod to match usual form
    - Added "use warnings", but that results in loads of warnings
      about functions redefined. So added "no warnings 'redefine';".
      Have to come back and work that one out!
    - Set all VERSION's to 0.96_01. I suspect a switch to Dist::Zilla
      might be coming soon...
    - Updated README to acknowledge change in maintainer
    - Reformatted as per CPAN::Changes::Spec
