This one line script generates  surface  data  for  gnuplot  from
grass:

    r.stats -1x $1 | awk '$2 != row{print "";row=$2}{print}'


You will need to capture the output into a "file",  tell  gnuplot
to  set contours, set parametric, set cntparam levels, set trange
to range of z values urange and vrange to range  of  columns  and
rows. Then splot "file" with line.

Of course some scripts could be written to tell gnuplot all these
values  automagically (except perhaps the contour level) based on
the data in "file"
