What can I use online to plot 2D and 3D diophantine equations?

Using the algebraic operations and equality, and (scatter) plotting the integer solutions, for example:



Plotting $x$ and $y$ for $x^2 + y^2 + n^2 = 9$



$(2, 2), (3, 0)$ and $(0, 3)$ are among the points that get plotted as $2^2 + 2^2 + 1^2 = 3^2 + 0^2 + 0^2 = … = 9$



I've tried W/A and Desmos with no luck. I've considered Rextester but the languages I'm much good at lack the ability to plot anything. With all the plotting/graphing related websites there must be a reasonably straightforward way of doing this.
