Graphing with the BGE

I was looking at 3DGuru’s Plotter and it was pretty simple and easy to use. But when I attempted to make something similar all I could do is have the responsive version of Python give me the value, I want to know how to make a visual.
I want to make a graphing system within the BGE through any equation to start me off, once I have one equation done all I have to do is replace the equation to program it to graph something else. For example the pythagoream theorem, I got the responsive version of Python to calculate one of the sides depending on which ones you enter in for the values, but the thing is, I want the BGE to create a scale model of the shape based on the integrated units.
Help would be greatly appreciated

Nvm I finally got it to work, just ignore this…
