Check out this talk by David McCandless.
David is the founder of the fantastic Information Is Beautiful website where you can find lots of infographics. Another good site for infographics is Good.Is. The iPad 3 infographic that I showed in class today is available at this link.
So for homework this week, to help prepare for creating your own infographic you should be researching infographics on the internet. Focus on answering the question 'how have they changed traditional maths graphs and charts to make the relevant and gorgeous?' I can't wait to see what you come up with!
