#big picture questions, motivation and relevance  But, actually, pie A single microbial community can be composed of many thousands of species, and the tools most commonly used (pie  charts are a problem because and stacked bar graphs) to visualize  the relative abundances of species in communities are inadequate. The  human brain is not good adept  at estimating area.

Instead, faces are perceived holistically, as a gestalt. Faces are infinitely variable, and we can quickly pick up on even very subtle differences and similarities between them.  Given that human brains are not well-equipped to interpret pie charts, how can we present microbial community data in a form of which we can make sense? The solution to this problem lies in a region of the brain called the fusiform gyrus.   This region of the brain allows us to process a particular, very complex image in an instant, undergoing relatively little decomposition into component parts. Instead, they are encoded via a holistic or integrative mechanism, as a gestalt.
