State transition graph representation of dynamics. a The nodes of all STGs (the set S) in a network with two genes that both regulate themselves and each other. b The corresponding embedding into two-dimensional phase space. c The discrete grid construction of phase space with constant Hamming distances from the extreme corners represented by color. d The projection of the states in the six-dimensional phase space of the EMT network to 3 dimensions corresponding to Zeb1, Snail1 and Ovol2. The colors divide this 3D cube into nine diagonals, each of which has a fixed Hamming distance from the extreme values representing E and M states. The E state is in the lower left-hand corner in the front, and the M state is in the upper right-hand corner in the back
