ragraph visualization problem

[Rashad Suleymanov via Argus-info]

Hi,
I am trying to run ragraph in Ubuntu 16.04, but getting following error:
Calling POSIX::tmpnam() is deprecated at /usr/local/bin/ragraph line 40.

It seems perl package has been deprecated, do you know how to fix it or
alternative to visualize it?
