Again I checked with some of the BANA & NBA Nemeth Committee members. The general concensus about your print example is as follows:
We really cannot think of a way to clearly represent this print drawing as a tactile graphic.
To separate it into layers of information seems to negate what they are trying to relay. It would be a wasted effort to try to represent a 3 dimensional coordinate system of this sort into a tactile graphic.
The first graphic labeled "Points in Space" could be briefly described after the caption is brailled, but I would not try to go into too much detail. I don't know if it is appropriate to suggest in a TN that a creative partner be sought out to demonstrate these diagrams with 3-dimensional models, but that is certainly what we would do in the classroom.
