Software for design 3D graph I'm looking for a software for designing 3D graph (graph with x,y,z axis).

I found OmniGraphSketcher but it seems that it allows me to design only 2D graph.

I don't want to use Matlab because my graph will not be a "mathematical" graph. It would be a graph with text and not dots or line or numbers.

I have to do something like the picture below but in a professional way.
Have you tried the built-in Grapher app in /Application/Utilities ?
