Explanatory power of visual proofs

Mathematics seems to have a special status when compared to other areas of human knowledge. This special status is linked with the role of proof, that is a formal argument allowing a unique level of certainty and leaving no room for unclarity. Nonetheless, mathematicians use other types of argumentation as well. Indeed, the ubiquity of computerized, intuitive, visual, analogical or metaphorical arguments in mathematical practice has been well documented.
