My circles are broad as well as narrow, depending on need. 2=2 is typically narrowly circular. Yet it can be broadly circular as art, a metaphorical partial imperfect mirroring across the diagonal encompassing a perfectly hewn = with imperfectly diagonally hewn 2s, allowing for the two halves shown together as a metaphor for chirality and why the Universe exists and is/cannot be in perfect balance and harmony. So, it depends.
