Metaphor and analogy in visualization
Curtis Wong of Microsoft’s Next Media Research group describes the architecture of information in three layers of what he calls a contextual pyramid: Engagement, context, and reference. Engagement draws the recipient in, context offers an explanation of the information source, and reference gives the ability to draw conclusions and connects to related resources. Metaphors and analogies are rhetorical devices which are used most often at the level of engagement, and can apply to concepts expressed through any form or medium.
