I don't know if this is foreseen, but it would be marvelous if
d.legend.vect could take into account the size_column*size (+ the -r flag)
and the width_column*width_scale info when drawing the symbols in the
legend.
I know this is much more complicated, and maybe this would warrant a
separate module, but being able to show the sizes of symbols in the legend
is a basic necessity when using these features.
A possible solution could be to find the min, mean and max values and to
create three symbols at their respective size that represent these values
(including writing the value into the legend so that one can understand
what each sized-symbol represents).
I imagine this would be way too much for the current GSoC, but I'm
creating this ticket so we do not forget.
