Schematic diagram of the main components in the percolated landscape of a flow network.

The core at the center comprises nodes in the strongly connected component (SCC) and edges within (SCE). The rest corresponds to peripheral components. Nodes in red belong to the in node component (IN) and the edge in component (ICE) is formed by red links. Nodes in blue belong to the out node component (OUT) and blue links form the edge out component (OCE). Both interfaces (ITF and OTF) appear in black.
