Code Issues Proposed changes

Fix error string interpolation

Browse Source 
The values were not correctly being interpolated
into the value error that is thrown when merging
graphs together and they have overlapping nodes.

Fix this by correctly interpolating and expanding
the messaging/reason why we do not support
overlapping graphs.
