An interesting definition of data visualisation, by Todd Holloway, with an example that compares the DNA dataset of monkeys with that of humans.
Graphic design is different from data visualization. Graphic designers are largely free from having to deal with actual data, and from having their product emerge from data. Graphic design components and data visualization components are often mixed, and with great success. But they are different. Art is not visualization. And visualization is not art… unless it is ;)
