2. I shall have to think in general, it is hard to predict. At the moment, we have a practical case that is, perhaps, surprising. We are trying to use dendron to build an exhibition that functions as a research map and mixes factual evidence with characteristic examples. I thought we could use the graph for navigation but note titles are too dry/abstract. So, an image and a line of arbitrary text would be good to begin with. Clickable links and tags might be a further idea. For more typical uses, dates, authorship, stats might be handy. For blue sky ideas, it would be cool to be able to animate this data by using parameters in sliders. Say, we could scroll through a history of the graph, especially if we have access to the git data. OK, this is probably beyond scope but just thinking...
