A diagram can be used to graphically demonstrate cause and effect in intelligent systems, in particular, expert systems. Diagrammatic Reasoning in AI explores the use of diagrams, or graphical representations, that show how something works or makes something easier to understand. In addition to static diagrams, the book examines more interactive and dynamic ones that are a central part of the user interface itself, providing researchers, programmers, intelligent systems designers, and web application designers with a broad range of topics for intro-advanced levels of understanding.
