I think we have all seen them…really bad charts that are so jammed with stuff that you can’t figure out what they are trying to communicate.

That’s why I really like the blog "Junk Charts." It offers up horrible charts and makes recommendations on how to make them better. And, readers join in with their suggestions. Check it out at http://junkcharts.typepad.com/junk_charts/

What is the worst chart you have ever seen?
