Robin Good: If you consider, like I do, "infographics" as visual presentation tools, I strongly suggest you to browse through this excellent slideshow by Robin Richards, which provides an overview of why infographics are important, gives a glimpse of their history, application and creation and gives a good insight on what makes them truly effective.
The secret key is in "using data" to tell a story, and NOT to paint a colorful poster of cute statistical charts.
Great examples and tips are all included.
