D.graph won't work because it only draws to an xdisplay.

But Tcl has a histogram command in the math and statistics library that will
accept output from a command like r.profile and create a nice line
graph/profile. This could also be done (with some additional effort) with
even more basic TclTk canvas draw commands.

Again, TclTk commands can simply read through a label file (it's ascii) and
parse the label parameters into canvas text objects. There is pretty much a
1:1 relationship between text object parameters and label parameters.

YES!
