I'm looking for a SIMPLE way to plot 3D equations. Is my only option Mathematica? I looked at gnuplot, but the manual stinks, I looked at MatPlotLib for Python, and it doesn't look like it can do 3D easily (if at all), and I just don't know where to look.
I've got some equations, and I can't visualize them myself, and hand plotting 3D sucks. I'm interested in what happens around the y axis and the origin. I know my equation converges on 1, but I need to see the part close to the origin, which is more chaotic.
Of course, I could program it myself, but I'd really like to avoid this if at all possible.
This is the best I've found so far :
