You'd have to modify some source code if you really want to do it.
You can set-up accesses and permissions using the applicationContext.xml and edit the WEB-INF/jsp/console/home.jsp to allow proper users to access the Monitor Apps section.
For the graph view thing, I believe your're talking about the Running Process Instance view where you can see where exactly is your process at, right? If that's the case, you could allow accesses to that view as well.
But, I think the monitoring section was created with the purpose that the Administrators who created the process would be the only ones that would understand how the process progresses and the end users would be abstracted and won't need to worry about what's happening behind the scenes.
Other than that, you can always tweak things to suit your needs, if you ever so wish it.
Thanks!
