1. A computer-implemented method for generating graphical representations of complex clickstream analytics, the method comprising: obtaining, by a server device, a plurality of clickstream datasets that each corresponds to one of a plurality of navigation sessions, each obtained clickstream dataset referencing one or more electronic documents accessed during the corresponding navigation session, the one or more electronic document references being ordered based on a sequence in which the one or more electronic documents were accessed during the corresponding navigation session; identifying, by the server device, a set of clickstream datasets, from the obtained plurality of clickstream datasets, that each reference a common set of electronic documents; determining, by the server device, a navigational pattern for the identified set of clickstream datasets based at least in part on a determination that at least a portion of the common set of electronic documents is referenced in a common order by at least a portion of the identified set of clickstream datasets; and communicating, by the server device and to a client device, a generated graphical representation of the determined navigational pattern.
