Possble to remove #card tag from graph view?

Hi,

I have a bunch of files that I have turned into flash cards wiith the #cards tag. The problem I encounter is that now in the Graph View all those files are related by the #card tag. This relationship is totally irrelevent to the subject matter. It just that they are all questions. Is there any way possible to tell the graph view to permanantly ignore that single tag? Otherwise either I have cards or I have a meaningful graph view. I want to have my cake and eat it.
