Three figures plotting individual dominating cycles for gene dataset \({\mathbb {D}}0\). These cycles actually reside in m-dimensions and are projected down to 3D using Principal component analysis. The colors indicate cohort phenotype labels \({\mathcal {X}}\in 0,1,2\). a Cycle 1 spanned by 15 vertices with 3 vertices having label 0, 7 vertices having label 1 and 5 with label 2. b Cycle 2 spanned by 10 vertices with 5 vertices having label 0, 3 vertices having label 1 and 2 with label 2. c Cycle 3 spanned by 12 vertices with 9 vertices having label 0, 3 vertices having label 1
