A key visual is a special kind of visual element (see also the post “Visualize as much as you can”) that provides additional structure for your document and additional guidance for your readers / listeners. The idea behind a key visual is to present a model, a process or some other kind of complex information in a visualized way as a graphical element. Then, the trick is to repeat this graphical element on the following slides while explaining the single parts of the model / process. While going through the different parts, it is recommended to highlight the one you are currently referring to. This way, your audience always knows where you are, what’s next and how the things you are currently explaining relate to the overall model / process. Sounds complicated? Well, it’s not. Just take a look at the example and you will get it immediately.
