The Global Map of Social Networking 2011 is a great example of successful experimentation with combining multiple visualizations into one. The map is used well to show general location, but it fades into the background since it is not the most important information. The bar charts show great data about quantity, and the venn diagrams show how those quantities overlap each other. In addition, since there are so many venn diagrams, they can be compared to each other like small multiples. It’s wonderful when combinations go so well together!
