Learning the language of understanding charts and diagrams is not obvious. From reading maps to understanding log-log plots, box and violin plots, etc. I mean there is a whole industry around this.

I think the ability to be able to transition in the same diagram to different semantic complexity levels is amazing. I want this for ALL of my communication and information mediums.

I am only commenting on the tools ability to zoom in and out from an abstraction level and not on the philosophy of how diagrams are constructed.
