3d plot of arbitrary xyz values. How to?

Hello. I am trying to make a 2d (e.g.contoured) or 3d plot of a height field given a set of (x, y, z) data. Is this possible with Matpolotlib? I’ve found many examples of F(x,y) data, and one which reads a DEM but nothing for a natural data set that is not in dem format.
Thanks in advance.

Google “python tricontour”.

Thanks! I’ll look it up!
