What's wrong with:
Show[
Plot[Sin[x], {x, 0, 10}, AspectRatio -> Automatic],
Graphics[Disk[{5, 0}, 2]],
PlotRange -> Automatic
]
note that the first Plot does not know it will be combined with another
graphics, so changing its plot range to Automatic you can't expect that
it will consider the disk of the other graphics. Show on the other hand
knows about all the Graphics it is combining. I think Show will
understand (almost?) all options of Graphics...
