1. A computer-implemented method comprising: receiving, from a user, a selection of a person and one or more relationships; to identify a context set within which the person may participate in transactions with one of a plurality of other persons; retrieving, using one or more processors, data packets aggregated from a number of sources transmitted over a network, to generate context set data that includes person data and transaction data based on the context set; generating, using one or more processors, a graph set by performing at least one set operation on the context set data; generating, using one or more processors a graph set file including graph set data by encoding the graph set; and rendering, using one or more processors, the graph set data into a visual format for display to the user, the visual format having a cluster with a star topology, the star topology having a center node representing the selected person and a plurality of peripheral nodes, the plurality of the peripheral nodes generated based on at least a portion of the context data, each node of the plurality of peripheral nodes representing the one of the plurality of other persons and connected to the center node via an edge, the edge representing the transaction involving the selected person and the one of the plurality of other persons.
