Re^2: Data visualisation.

Well, I thought that providing code that actually attempts to solve the problem and that shows that the data is not valid would be useful to you and to others (even though it is only a partial validation, since it is looking at distances only to A, B and C, not to other points, but it is easy to extend it if needed).
It was fun anyway to try to solve the issue, in a subject-area quite far away from what I am doing daily with Perl. I enjoyed it. Thank you for that.
