Schematic alluvial diagram of a multilevel network structure. a A weighted network with modular structure, organized into a two-level solution in b. c An alluvial diagram representation of the solutions in panels b and d using the same colors. Columns of blocks represent modules with heights proportional to the contained flow volume. The leftmost column is an ordinary two-level alluvial diagram representation. The multilevel representation to the right shows multiple levels, with the background showing the top-level organization. Stream fields connect modules in the left and right columns that share nodes. d Multilevel solution of the network in e
