What is true of it
Edim7 is E, G, B♭ and D♭ — 1, b3, b5 and bb7 counted from E.
The easiest of the 5 fingerings below is 012020: 3 fingers, held at the 1st fret.
2 of them use open strings, which is what makes a shape quiet to change to.
Where its notes are on the neck
The brass dots are E, the root. Everything else is a chord tone with its degree printed in it.
