From the creator of the infographic:

Marcus Evans Gipfel 2010 Summits Overview

“Currently companies are facing challenges to stay as profitable and efficient as possible. The GIPFEL series of summits help companies throughout Europe to meet the challenge and offer approaches to implement radical cost saving initiatives without affecting their operation, flexibility and productivity.

This infographic by Marcus Evans is to convey information about the business conferences around the world by who are the most popular delegates, what their jobs are, and where it creates the most social engagement.”

Because this infographic is so niche, I’m just going to talk about it generally.  Overall, it is well-designed, and the information is relevant in the context of the creator’s business.
