Take a look at this nice bit of data journalism done by the Wall Street Journal entitled United States of Venture Capital. It’s a nice interactive map that demonstrates a good way to show multidimensional data on a map using filters and category selections. This is the kind of stuff that Tableau handles very nicely. And, in case you were unawares, there’s the Tableau public offering that you can use (just remember that all your data will be public as well.)
So, when you’re composing your response to our FoodFacts.com challenge, keep Tableau in mind for that batman-style visualization utility belt you use for great visualization creations!
