There are numerous ways to visualize mail data. You could bucket messages by time and present the data as a bar chart to inspect the time of day that the most mail transactions are happening, create a graph of connections among senders and recipients and filter by the discussion thread, load query results onto a time line, or use any number of other techniques. This section demonstrates out-of-the-box usage of the SIMILE Timeline, an easy to use (yet extremely powerful) tool for visualizing event-centric data. The SIMILE Timeline is particularly useful for exploring mail data because it allows us to view the transmission of each individual message as a unique event while also visualizing the larger discussion thread as an extended event that transpires over a longer period of time. We can also easily specify a link for each individual message so that when we click on a message in Timeline, it brings up the full text of the message in Futon.
