My only issue with this graph is that it assumes that each faction of an alliance has the same feelings about the relationship. For instance, at the intersection of Tau and Space Marines, it indicates "Brothers in Arms." I think the graph would work better if each box was divided diagonally, such that in my above Tau/Space Marine example, the Tau might consider the Space Marines "Brothers in Arms," while the Space Marines would only grudgingly ally themselves with the Tau.

On the plus side, this gives canonical precedent to the story I'm putting together, which involves a squad of Space Marines being forced to work alongside a small Tau contingent.
