Transmediation is a process of bringing meaning from one sign system to another. Transmediation is the basis of all literacy and it’s the essence of media literacy. Graphic art, sculpture, dance, music, photography, all are bearers of meaning, and each medium constrains the types of messages it can express. Every sign system has it’s own grammar.

Take graphs, for instance.

About a month ago John Pederson posted a graph on his blog about rate of change in education. Tom Hoffman commented, and left a trackback that he called Graph Troll (Tom’s blog had a meltdown and we can’t see his post now. He’s got a new blog running here.)

I thought about how graphs might be useful for communicating all sorts of messages - like opinions - not necessarily empirically validated. It seemed like a good idea for a blog, but I didn’t have any messages that demanded graphic representation. I forgot about the idea.

Until Kevin linked to Indexed. It’s a GREAT graphic blog. It’s smart. It’s funny. The author, Jessica Hagy, uses graphs and diagrams to produce cultural commentary. Good stuff.
