I find the new logic of this method a bit confusing. Why do you set some
configuration parameters here (degrees and direction) and the rest in the
helper methods?
As far as I understand, you have 2 cases that matter here: the degrees
option is set or not. This defines whether you create a simple vertex or you
augment it with degree information, right?
