Here is a set of “visualizations” to make you think a little bit about what a visualization is (or can be).
Christoph Niemann is an illustrator who has a semi-regular column/blog in the New York Times. Some of his work is really funny. All of it is clever. Have a look at some of his work – there are links to his posts on the sidebar of any of the NY times pages.
In the comments, give your thoughts on his work. In particular, what ideas about visualization might we learn from it?
