Organise graphs based on purposeful views

[psjm3]

Currently users select which graph to generate by issuing a command line option, to make it more intuitive we could organise the options into "views", such as "Compartments-view", "Threads-view", "Heaps-view", etc. Users can first go to a view, and then interactively generate graphs based on information they want to get from the views.

Perhaps we could have a web interface where view options can be selected, and when a view is displayed, users can zoom in and out of the view or click on the nodes to drill down on that specific compartment or thread, etc.

Copied from @rwatson's suggestion on slack:

"I have been pondering visualisations a bit, and I realised that it might be that we want to think about “views” of some sort -- e.g., “compartment centric”, “thread centric”, (perhaps) heap-centric, and so on. In a compartment-centric view we’re interested in the rights accessible from (and to?) thread stacks, but not so much that we’d arrange the whole layout around it. Whereas in a thread-centric view, I think we’d try and lay out all the disjoint stack bits associated with a single thread in vertical “stacks” perhaps with a thread ID / name above, etc.
This might help us focus the ambitions of particular plots a bit more, making it easier to figure out how to arrange them, what to elide/combine/etc."
