```Yes!; but you may not like the answer:

. graph7 mpg, box by(foreign) vw

How to do this is discussed within

explains how to use egen to calculate the statistical
ingredients needed for box plots and variations of box
plots; shows the use of twoway to then create the plots

but there is no easy solution that I know. You would have to superimpose several -twoway-s to get there.

A colleague has shown me a couple of box and whisker plots where
the width of the box (that is, the dimension that is perpindicular
to the whiskers) is proportionate to the number of observations the
box represents. I think it's a useful modification, and have been
trying to create this myself. However there seems to be no option
in -graph box- to control the width of the box.

Is there a graph type and option combination that I am overlooking
that will allow me to create box and whisker type plots while
controlling the widths of the individual boxes?
