The information design patterns application is a collection of 55 design patterns that describe the functional aspect of graphic components for the display, behavior and user interaction of complex infographics.
For each pattern, you’ll find an extensive description, a layout example and a real-world example. A left menu allows you to see other patterns that have a relation with the one you are watching.

This amazing work has been accomplished by Christian Behrens, a Berlin based designer, for his thesis about the development of a design pattern language for interactive infographics.
Although it is quite different, this made me think of the Yahoo! Design Pattern Library, a much appreciated documentation provided by the Yahoo! developer network. Focused on webdesign, you’ll find there the answer to most common website or application design issues.
