I read this BusinessWeek article today about the work of Martin Wattenberg, a data visualization expert. The article includes a gallery of charts some of which show data in very interesting and unique ways. I think Edward Tufte would approve.

I particularly like the highway vs city mileage chart that opens the montage and think this is something that might be of use in a digital-dashboard-type setting. I've seen this type of chart in other places and think that it could be a powerful way to display relationships. For example, one could use a chart of this type to show something like late shipments vs volume of shipments to customer vs number of shipments vs product category.

I also like the way that Wattenberg crafts his charts. All of the featured charts have an interesting ascetic, especially (IMHO) the NameVoyager and
Many Eyes charts.

There is another BusinessWeek article that describes a web-based tool created by Dr. Hans Rosling to show the relationships between per-capita income and life expectancy. The most interesting aspect of Rosling's chart is his use of animation to show change over time.
