Described herein is a computer implemented method comprising: generating a state transition replay request defining a time period and object selection criteria and communicating the state transition replay request to a server. In response to the state transition replay request replay data is received including starting state data indicating a starting state of objects satisfying the object selection criteria at a start of the time period; and transition data indicating state transitions of objects satisfying the object selection criteria over the time period. The replay data is used to display a transition replay interface in which a transition replay is displayed.
