In order to visualize the fretboard, it's a good thing to learn the chords and their inversions.
Below you can see a Dmaj7 chord in root position and it's three inversions. What does it mean?
- Root position: root in the bass
- 1. Inversion: 3rd in the bass
- 2. Inversion: 5th in the bass
- 3. Inversion: 7th in the bass

Construct the root postition 7th chord and it's three inversions for D7, D-7, D-7b5.
The difference between Dmaj7 and D7 is just the 7th. (Dmaj7 = major 7th; D7 = minor 7th).
The difference between D7 and D-7 is just the 3rd. (D7 = major 3rd; D-7 = minor 3rd).
The difference between D-7 and D-7b5 is just the 5th. (D-7 = natural 5th; D-7b5 = diminished 5th).
