I am looking for (preferably free) software to:
1) plot 3d points read from a file. A scatter plot would be fine.
2) Optionally color the points by a property – also read from the file
It would be terrific if this program could also compute and display the best fit plane through these points.

There are quite a number of freewares which do that.
Hope you'll find your best choice here !!! Good luck, Sébastien
