As for how I want Hieroglyph to work interactively, I think the easiest way is to react to the input data considered as a coherent whole. The semantic model for visualization is that a Visualization is a function from Data to Visual.

Hmm, doesn’t this approach result in scalability problems? You always have to analyse the complete input data if a small part of it changes and you always have to update the complete picture. This is similar to the problems I see with Yampa-based UI approaches. However, you might be interested in things like incremental list signals which I’m (re-)implementing at the moment. To a large degree, the library user sees a time-varying list but internally the library takes care of not updating the whole list all the time but only the parts which actually change.

The main problem I have, which is what I want FRP for, is that to consider the data as a coherent whole, the data have to be composable.

I don’t really understand this. Could you explain this, please? Best wishes, Wolfgang
