What is true of it

Bdim is B, D and F — 1, b3 and b5 counted from B.

The easiest of the 5 fingerings below is x20401: 3 fingers, held at the 1st fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

1 string stays silent.

The brass dots are B, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
