is Cyclooctatetraene dianon aromatic?, i.e. is it planar?. is the ring flat?

What is the law that a molecule is aromatic?

Correct, You have 3 double bonds and 2 Electron pairs from the two charges.

If you count you have then 10 electrons. This fit to 4*n + 2 if you take n = 2 and so its aromatic.

Odd number of Pi bonds/lone pairs and uninterrupted set of P orbital bearing atoms.
It looks aromatic to me.
