The infographic below is part of the post The Top 50 Most Visited Websites in the World which is a wonderful example of how an infographic can be used to share a great deal of information in a single image. This is a great infographic and even though some may argue that it has too much information you need to take into context just how much information is being summarized. Other than the legend and the labels there is very little text and in a few seconds you can determine which site is the most visited.
