While it may be somewhat tenuous to let a single text represent an entire language group, I see in the first graph that the last two Latin texts are quite similar. The other Latin text would have been written by an English Norman.
In the fourth graph, there is a strong similarity between the VMs and the Italian 'Fabula'. Where does the 'Fabula' show up in the dots?
