Visualizing social interaction with simple shapes and vectors.

(The definition of reciprocity: "the practice of exchanging things with others for mutual benefit, especially privileges granted by one country or organization to another.")

The essential nature of these interactions should be evident at a glance. The true complexity of social dynamics are not revealed this way, but at the very least, some of the salient characteristics are demonstrated: 

• indirect reciprocity: benefit passed on to an unknown connection in the future
• direct reciprocity: immediate shared benefit 
• self-interest (non-reciprocal): insular benefit 

When these visuals are combined with more information and other elements they work like mnemonic devices that enable comprehension the more complex the data map becomes.
