15. A system for graphically representing a subset of a plurality of health care data categories to a health care plan member via an online health care category node map, the system comprising: a database for storing (a) a health care data taxonomy relating health care terminology to one or more of health care benefits terminology, health care-related financial terminology, health insurance terminology, and dental insurance terminology, and (b) a dynamic member profile for the health care plan member; a server for initiating a display of the online health care category node map, the server comprising memory having stored thereon computer executable instructions for: receiving an online member identification token associated with the health care plan member; identifying the subset of the plurality of health care data categories based on correlating the health care data taxonomy with the member profile corresponding to the online member identification token; initiating the display of the online health care category node map, the display comprising a ring node topology of health care category nodes disposed along a loop-shaped wireframe structure for graphically indicating a relationship between adjacent health care category nodes within the subset, the online health care category node map responding to member input that selects a category node by orienting the ring node topology display around the selected category node by way of automatically rotating the health care category nodes along the loop-shaped wireframe structure so as to accommodate expansion of the selected category node into subcategories; and wherein at least one category node in the online health care category node map comprises one or more subnodes corresponding to one or more health care data subcategories, the at least one category node expanding into the one or more subnodes responsive to member input that selects the at least one category node.
15. A system for graphically representing a subset of a plurality of health care data categories to a health care plan member via an online health care category node map, the system comprising: a database for storing (a) a health care data taxonomy relating health care terminology to one or more of health care benefits terminology, health care-related financial terminology, health insurance terminology, and dental insurance terminology, and (b) a dynamic member profile for the health care plan member; a server for initiating a display of the online health care category node map, the server comprising memory having stored thereon computer executable instructions for: receiving an online member identification token associated with the health care plan member; identifying the subset of the plurality of health care data categories based on correlating the health care data taxonomy with the member profile corresponding to the online member identification token; initiating the display of the online health care category node map, the display comprising a ring node topology of health care category nodes disposed along a loop-shaped wireframe structure for graphically indicating a relationship between adjacent health care category nodes within the subset, the online health care category node map responding to member input that selects a category node by orienting the ring node topology display around the selected category node by way of automatically rotating the health care category nodes along the loop-shaped wireframe structure so as to accommodate expansion of the selected category node into subcategories; and wherein at least one category node in the online health care category node map comprises one or more subnodes corresponding to one or more health care data subcategories, the at least one category node expanding into the one or more subnodes responsive to member input that selects the at least one category node. 17. The system of claim 15 wherein the memory further comprises instructions for displaying one or more hyperlinks to content associated with the one or more subnodes.
