Last week i had a really nice day at the Airline Forum 2010, which is a conference hosted by Lufthansa Systems. Many impressive new things where presented.
I was invited to give an introductory talk to visualization. These talks I actually like a lot since you can really surprise people with nice and impressive pictures. A very famous picture, surely everybody in visualization community should know is the graph of Minard visualizing the march of Napoleon on Moscow. For me the birth of information visualization.
