@bibek dash : I can not draw "anything".
@ All: I click and drag to write something but all it shows is a polygon. What to do to write "N" in the figure.

Peter Grey

extremely useful elegant piece

Joseph Marks

It is very good.

A few "nits":
In the help for the function, it implies a non-existant argument, x,which should be cleaned up.

Also, I personally dislike the "convhull" that redoes what is drawn "freehand" ; I removed it, but this wasn't completely trivial.

None-the-less, a really, really, great GUI file!

These comments are my own and not my organization's.
