MathFilter: Help me calculate the location of points with lots and lots of distances.

Say I have a list of points A, B, and C. A is x away from B, B is y away from C, and A is z away from C. This is relatively straightforward to visualize as a triangle and compute with free tools online.
However, I have 12 points, and a list of the distances between each point and all of the others (in the form of real numbers, so A to B is .96, B to C is .85, etc. multiplied 144 times). I've been trying to find something online that can make this into a visualization but perhaps it's way too complicated?
I'd really like some sort of representation of the points in space that I can label. (It's for a cool project on language distance I did, but it's been years since I've done complex math and I'm struggling on this part).
