I've come up with a curious two-part question while working on a map program:(adsbygoogle = window.adsbygoogle || []).push({});

What is the minimum number of points necessary in order to transform an NxN adjacency matrix into a coordinate matrix in terms of N given Euclidean space?

As this question relates to map-making, where I don't believe the parallel-postulate holds, what is the minimum number of point necessary for this transformation on the Earth's space?
