About graceful degradation, indeed, in my compressor example, you would

certainly have regular controls aside of the interactive visualization area.

Setting the threshold could be done graphically but also with say a knob. So it

would still work if direct access to waveform data is not available, the

visualization would be deactivated.

This sounds nice and solves the rich-visualization issue IMO.
