My gut feeling is to keep it simple at this stage: make the svg class "write
only" so we can use it to create basic diagrams, but can't open/modify
existing ones. I don't want to distract you too much from your core aims of
visualising data - and a fully fledged DOM is probably unrealistic within
the timeframe anyway - but it seems a shame to have this class, and not have
it useable at a user-level.

HTH, John.
