This depicts an Em/G chord. The Whiteboard G6 Chord was used to come to the conclusion that a ‘6’ could replace the letter ‘G’. We do not yet have a solid explanation for this chord, which is identical to the G6 chord except the fourth string is changed from a D to an E.
You could play it as a G maybe
black filled in means string pressed and not filled in (open) means open string (not press)
