11.13Circle of Fifths gives you the roots

Look at:

D → G → C

D → G → C

Roots descend by fifths.

Then:

A → D → G

A → D → G

Then:

E → A → D

E → A → D

So the Circle of Fifths already contains every ii–V–I route.

ii–V–I in C (Dm7 → G7 → C) is two counter-clockwise steps on the circle

This is one reason your original chord chart is so useful.
