This chordmap idea has been a blessing to me in the last 12 years when my songwriting output changed by an order of magnitude. Note how diminished chords always pass into a larger shape and they don’t lie on the main trunk. http://www.readmusicfree.com/images/chordprogressionmap.png

Note. No augmented chords on that major map!

Oh, btw, the way to use the map is to start a progression out away from the trunk and follow the branch in and down the trunk to the root.

Pretty slick!
