3D Graph is a free software tool designed for visualizing equations and generating both 2D and 3D graphs. It simplifies the process of graphing mathematical functions.
It does nothing other free programs cannot do. It is limited to f(x,y). Practically everything is limited.

Pros
Simple and yet powerfull tool
<p>Easy to use - it is quite self explanatory
<p>Most functions I needed were there
Cons
Completing features for this product would be Min/Max point finder, derivative calculator and other useful calculus tools... but still it does exactly what it claims... 3D Graph
Visualize equations and create 2D or 3D graphs.Draw 3D or 2D equation with this equation graphing free software. Visualizing equations is made easy with 3D Graph. To draw 3D or 2D graphs all required is filling in the equation of the form z=f(x, y).
