Aromaticity is indicated by a circle inside the ring. The circle indicates that all the bonds are equivalent.

The most common aromatic compound is benzene.

Benzene is a resonance hybrid of two contributors.

It doesn't consist of alternating double and single bonds.

Rather, every bond is a 1½ bond.

These partial bonds are indicated by dashed lines.

For simplicity, the dashed lines are usually drawn as a dashed or a solid circle.
