A scale diagram represents the fretboard of a guitar. Just like a guitar tab, the bottom line of the guitar scale diagram represents the low E string.
The red dot on the 3rd fret low E string shows the root note G. Follow the arrows in order to play the notes of the G Major scale on the guitar. The second red dot on the 5th fret of the D string is the octave root note.
