Researchers at Vienna & Austria have developed a new event visualization algorithm called “Event Tunnels”, and they’ve just released a report on it and how they were able to use it to visualize automated fraud detection in online betting and real-time monitoring of logistics processes. InformationAesthetics describes it as so:
The data visualization technique is based on the metaphor of considering the event stream as a cylindrical tunnel, which is then presented to the user from multiple perspectives. The “top view” looks into the stream of events along the time-axis, so that events on the inner circles of the tunnel are displayed smaller to simulate perspective projection. The angular position of each event is not implicitly defined and can be controlled by the business analyst with placement policies. The “side view” plots the events in temporal order, and resembles process charts such as GANTT diagrams without the depiction of dependencies.
Looks interesting, and the PDF is available online here.
