notebooks - How to center a graphic in its output cell

Say I have produced a single graphic ouput, perhaps a plot. Instead of displaying left-aligned in the notebook, I would like it to display in the center of the output cell. I would like it to stay centered if I change the magnification. I would like it to be centered when I export to PDF.

Possible?

Answer

You can also use Pane/Framed etc. + Full width + Alignment:

Pane[
 Graphics @ Disk[],
 Full, 

 Alignment -> Center
]
