Lets Define Information Design...
Information design is the ability to create order. It is a visual means of explaining and interrupting complex information and data to assist the user to achieve a specific objective. It is primarily concerned with clarity and accuracy, it revels the data rather then hiding or simplying it.
Information design graphics provoke the viewer to think about the substance of the data not about the design, therefore the information has to be designed clear, effective, and understandable.
Examples:
There is many different styles and forms of information design some examples I can run off the top of my head are things such as: stock market graphs, telephone bills, road signs, instruction manuals and street maps.
Below are some visual examples of Information Design graphics:
