In some embodiments, a request to filter information associated with activities within a network environment is received in response to a user interaction with a graph that comprises a plurality of nodes. At least one node included in the graph is associated with an activity within a network environment. As one example, the request to filter is triggered by a user interaction with a visual representation of at least a portion of the graph. As another example, the request to filter is triggered by a user interaction with a query field. In response to receiving the filter request, a query is generated based on a join using a query service.
