Sorry for the late reply. Not all prio could go to Obsidian the last days 
The question is if I have to use the [[]] or what are the advantages because I tend to get the same graphs with or without them.
The scripts generates a “MOC” that has the name of the isolated term and inside all the references to the files (between [[]]) that contain the term to be isolated. When I do a local graph of this I get the result as shown.
The same happens when I do process the files and additionally put the term I want to isolate between [[]] (which I understand as backlinkling) in the files that contain the term to be isolated.
So I was wondering what the added benefits were because if you have lots of terms to isolate the readability of the processed file becomes a little bit of an issue in editors outside Obsidian and inside Obsidian when in edit mode.
