I’m always a little bit wary of info graphics, largely because as a scientist/mathematician I want to see the raw data too, just to make sure sure I agree with the presentation of the data. However, that doesn’t mean that all info graphics are incorrect and they are increasingly more popular, so teaching students to evaluate them is an important 21st century skill.
The Aside Blog has a fantastic page full of links to various info graphics for you to use in class. I also love the video they highlight by Column Five which talks about specific visualization strategies for presenting data. So if you’re interested in data visualization and info graphics, head on over to the blog and start indulging your inner data geek.
