I work in the database world. The software I work with is pretty cool at doing data visualization, that is, taking lots of records chock full of lots of data and displaying it in such a way as to make it meaningful to someone attempting to analyze it. Sometimes all it takes is a grid. Sometimes pictures speak louder than words. Here is an excellent example given by Dr. Hans Rosling from the BBC program The Joy of Stats that everybody can relate to using not only a ton of data, but a ton of data collected over a very long period of time. I remember my college statistics experience being very painful. Good visualization methodology properly used makes all that pain go away.
