Technology is disclosed for controlling the processing and presentation of user-connection data on computing devices to provide improved electronic communications applications and user computing experiences. User-connection data may be programmatically determined or inferred from the user data for a plurality of users. The user-connection data may be assembled into a graph data structure, which may be further processed to determine optimal paths connecting users and to derive information insights. Aspects of information insights may be presented to a user and/or consumed by a computing application or service to provide an improved user computing experience.
