```Walt,

-graph pie- supports weights.

. sysuse auto
. sum foreign

Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
foreign |        74    .2972973    .4601885          0          1

. graph pie, over(foreign) plabel(_all percent)
. sum foreign [aw=weight]

Variable |     Obs      Weight        Mean   Std. Dev.       Min        Max
-------------+-----------------------------------------------------------------
foreign |      74      223440    .2280254    .422423          0          1
