A system for visualizing an information network. A database (DB) contains node descriptions and connection descriptions that collectively define the topology of the information network. A rule set (RS) relates at least to the topology of the information network. First user input means (IN) receive a navigation input (NI) and a definition a set of focus nodes. Second user input means receive filter settings (FS). Selection means (RE, FR) dynamically create one or more subnetworks based on the set of focus nodes, the topology of the information network, the rule set (RS) and the filter settings (FS). Layout generation means (LG, BF, ZP) dynamically generate a layout for the subnetworks.
