Shapes and Patterns in Visualizing Human Knowledge
The concepts of knowledge presentation have their origin in the early Middle Ages and establish contemporary trends in visualization activity. Using the latest scientific observations, it is possible to conclude that circles and spheres are the most common natural shapes in both micro- and macrospace. The next most often used metaphor in medieval literature is a tree: an instance of fractals that today determines the geometry of nature. The fractals are the strong attractors of human mind space. The problem is how these two forms interact with each other and how they coexist in the context of effective visualization of information. The chapter presents an intercultural historical outline of appropriate graphical forms for knowledge representation. The authors strive to prove the main hypothesis: fractals and spheres contribute to modern complex visualization. The reasons may be sought in human perception and cognition. This chapter discusses visualization problems in the form of tree-like fractal structures embedded in spherical shapes over time, different cultures, and inter-personal relationships.
