Show Tags as Nodes in the Graph

[isiko]

Is your feature request related to a problem? Please describe.
I link my Nodes by using Tags, so in the current implementation a lot of my Nodes are Orphants

Describe the solution you'd like
Like the normal 2D Graph, a Solution would be to add a Node for Each Tag (toggleable by a Filter maby) and then Link all Files that use that a given tag to the corresponding Node
