“This article discusses two key ideas. First, it briefly outlines four ways to represent the same information. Second, it provides a high level overview of Perceived Information Architecture… These four modes of representation are interesting because they are at the same time very similar and very different from each other. They all basically represent exactly the same information. However, the first mode affords flow, the second mode is visual and inclusive, the third mode is extremely compact, and the final mode is driven by language.”
