To be honest, I find any dynamic or interactive changes to technical diagrams as distracting. For me the benefit of pouring more info via dynamic popups or animations is lost due to lack of static info that can scanned back and forth while I try to understand the thing, just by looking at it. I need the diagram to stay static and not force my way of understanding to fit into the interactions or animations.
This is a great point and not one that I had considered. I suspect I am the same way - scanning back and forth while studying a diagram.
It's possible this tool may be more appropriate for e.g. presentation of info to a mixed audience. Technical people may have questions that can be answered with detail that non-technical people would find distracting, if it were visible on the main diagram. And "presentation" here could be a literal presentation in a conference room, or documenting something on a site that people visit on their own.
You could make the argument in that example that you should create two diagrams, one for each audience. I think that is a valid argument - but I can also imagine maintaining two separate diagrams that present similar information could be irritating.
