The rhizome operates by variation, expansion, offshoots. Unlike the graphic arts, drawing, or photography, the rhizome pertains to a map that must be produced, constructed, a map that is always detachable, connectable, modifiable, and has multiple entryways and exits and its own lines of flight. In contrast to centered (even polycentric) systems with hierarchical modes of communication and preestablished paths, the rhizome is an acentered, nonhierarchical, nonsignifying system, defined solely by a circulation of states.
