Well, different kinds of diagrams show different things.
"Collaboration diagrams" might show connections and how things work together.
"Inheritance diagrams" might show what is a subset of what, or what evolved from what.
"Sequence diagrams" show the order in which things happen.
That drawing seemed like a list of entities or techniques: a toolbox that is mainly a list of tools.
Maybe different diagrams would list many of the same things, but the different organizations would show different ways of looking at the same set of things. It sounds as if permaculture is usually a highly integrated practice, so that any one organizational scheme would necessarily offer only one perspective at a time, about a subject that is by its nature too complex to understand from any one or two viewpoints.
You might have to look at it with one eye, then the other eye, then in a mirror, and then standing on your head to see all the inter-relationships.
