For instance a 3d graph of events vs process over time. - tptp demonstrated (the 10 minute unintended demo was far more useful than the slides) zomming in/out using drag select to give that high-level view and then zoom in Typically the UI was using SQL queries to extract/filter the data before visualizing it.
