That is super cool.

But as a sort of tangent / related thing:

As a visual learner I don't feel like I usually have problems visualizing SQL (that doesn't mean I wouldn't have use for this product, quite the opposite).

On the other hand I personally have been playing with Firebase and OH MAN do I have problems visualizing what is going on with document type databases, I start writing code and think of the DB and my brain starts sputter like there's sand in the gears ;)
