I have no short-cut here. You might need to specify the corner
coordinates for each tile. I wouldn't rule out running into limits
within -graph-.

I really wouldn't recommend trying to do this in Stata without an
algorithm to do the tiling, but conversely source code for tree maps
should be accessible somewhere and should be translatable into Stata
or Mata.
