1. A method for analyzing and facilitating an understanding of event data, the method comprising: receiving, at a server, a subject event identifier entered as user input via a user interface displayed by a client device; accessing event data stored in a network database in communication with the server, the event data including a plurality of event data records, each of the plurality of event data records corresponding to an event and including a set of participant identifiers corresponding to participants in the event, the plurality of event data records including a data record corresponding to a subject event identified by the subject event identifier; determining, using the one or more processors, an event participation flow associated with the set of participant identifiers corresponding to the subject event using the event data, the event participation flow of the set of participants including a transition of participation from one or more preceding events to the subject event and from the subject event to one or more subsequent events; causing presentation of a graphical representation of the event participation flow in the user interface displayed by the client device, the graphical representation including a plurality of graphical elements to represent the transition of participation from the one or more preceding events to the subject event and from the subject event to the one or more subsequent events, the plurality of graphical elements including: a first graphical element corresponding to the subject event, the first graphical element including an indication of a number of participants that participated in the subject event without participating in a preceding event, a second graphical element corresponding to the preceding event, a third graphical element corresponding to a subsequent event, a first connector element connecting the first graphical element to the second graphical element, the first connector element representing a first flow of participants, the first flow of participants including a first number of participants, the first number of participants having participated in the preceding event and the subject event, a width of the first connector element representing the first number of participants; and a second connector element connecting the first graphical element to the third graphical element, the second connector element representing a second flow of participants, the second flow of participants including a second number of participants, the second number of participants having participated in the subject event and the subsequent event, a width of the second connector element representing the second number of participants; receiving a user selection, via the user interface, of a category filter, the category filter specifying an event category; and in response to receiving the user selection, filtering the graphical representation of the aggregate event sequence, the filtering of the graphical representation including updating the graphical representation to include a subset of the plurality of graphical elements corresponding to events of the event category, the updating of the graphical representation including removing one or more graphical elements from the graphical representation in accordance with the category filter.
