In fact, we can do considerably more now with the wxPython (and TclTk)
drawing commands to than is available in d.graph or d.linegraph, even with
your nice enhancements.
In the case of histogramming and profiling, it seems a better display to
have them come up in a separate window (like is now the case with the TclTk
profiling module) than have them rendered like a map in the main display
(like we do now for d.histogram in the current TclTk GUI). Rendering maps is
complex and it doesn't seem efficient to have to go through the same complex
procedures to draw a histogram or profile that doesn't need to be drawn
For this reason, it seems better to do these kinds of analyses with the gui
tools, using underlying GRASS modules like r.profile and r.stats.
