- 11. Art & Science
- 12. What’s Missing? Doing data visualisation well is less a technology problem, more a people problem. Paraphrasing Aron Pilhofer, New York Times
- 14. So, why the ‘8 hats of data visualisation design’?

- 16. Mr Benn, a man wearing a black suit and bowler hat, leaves his house at 52 Festive Road and visits a fancy-dress costume shop where he is invited by the moustachioed, fez-wearing shopkeeper to try on a particular outfit. He leaves the shop through a magic door at the back of the changing room and enters a world appropriate to his costume, where he has an adventure (which usually contains a moral) before the shopkeeper reappears to lead him back to the changing room, and the story comes to an end. Mr Benn returns to his normal life, but is left with a small souvenir of his magical adventure. http://realtimeshortstories.files.wordpress.com/2011/10/mr_benn.jpg | http://www.youtube.com/watch?v=FMSJNrzQ3PM

Editor's Notes
- I’m going to briefly present some contemporary visualisation projects from prominent designers across the globe and pick out some key tips learned from each to help achieve effective and efficient visualisation results.
- If we take another look at Google Insights, this time for the term Infographic, we see a similar trend of interest.

- You’re also expected to be a super hero with all the abilities perfectly aligned, balanced and deployable at a moment’s notice. It’s just not that likely, so you will usually rely on a team. The advice I received from most people was ‘stay close, connected and together as a team’.
- Six Thinking Hats® is a simple, effective parallel thinking process that helps people be more productive, focused, and mindfully involved. And once learned, the tools can be applied immediately!You and your team members can learn how to separate thinking into six clear functions and roles. Each thinking role is identified with a colored symbolic "thinking hat." By mentally wearing and switching "hats," you can easily focus or redirect thoughts, the conversation, or the meeting.
