Here's a simple test drawing that does exactly what you want. Change
the filename root(fnRoot) and/or the output directory(outDir) to suit

#Autogenerated by ReportLab guiedit do not edit
from reportlab.graphics.charts.piecharts import Pie3d
from reportlab.graphics.shapes import Drawing, _DrawingEditorMixin

class TestDrawing000(_DrawingEditorMixin,Drawing):
        def __init__(self,width=400,height=200,*args,**kw):
                apply(Drawing.__init__,(self,width,height)+args,kw)
                self._add(self,Pie3d(),name=None,validate=None,desc=None)
                self.contents[0].x            = 25

if __name__=="__main__": #NORUNTESTS
        TestDrawing000().save(formats=['png'],outDir='.',fnRoot=None)
