Redmine

Hi All,
Greetings. I am upgrading our redmine from 2.5.2 to 3.4.5 on a different VM (RHEL 7). While I have configured most of the plugins, I am stuck with wiki page that loads a graph and image. For some reason I am not able to efficiently use or configure wiki_graphviz_plugin. Could someone please help, I guess I am missing some configurations here.

I had asked the IT team to install graphviz software as I did not have root access and I could not install the software because of permission issues.

Attahced are the screenshots of wiki page in old redmine (where it works fine) and new server where it is not.
