Matrix visualisation of simple connection degree network partitioning. DAG matrix for genome-scale network of Arabidopsis thaliana after applying connection degree partitioning with different cutoffs. Subnetworks are displayed as non-overlapping blocks (coloured pixels on blue background) for connectivity threshold value (a) 20 (b) 10 (c) 5 and (d) 4. Large values leave a monolithic unresolved block, while small cutoffs produce extensive fragmentation.
