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.
