Abstract: Non-limiting examples of the present disclosure describe examples of data visualization, where data visualization representations may be generated to visually represent aggregated data for a service from the perspective of a user. The data visualization representation aggregates data of the service into points of interest that provide user-centric perspectives of the service data. Points of interest may comprise but not limited to: individual data streams, channels pertaining to groups and/or teams that a user is associated with, messages, postings, mentions, chats/conversations, emails, meetings/events, social networking connections, documents, task items, reminders, data storage and media content, among other examples. An exemplary data visualization representation is designed to organize a large volume of service data for the user, direct attention of the user to content that may be of importance to the user as well as enable a user to initiate an action through the data visualization representation.
