Key information about each Enneagram type was collected, systematised and visualised. It is based on the works of authors who played a crucial role in the development of the Enneagram as a modern psychological typology. Among them are Oscar Ichazo, Claudio Naranjo, Don Richard Riso and Russ Hudson.

All information was organised into six lists: comfortable/uncomfortable conditions for the personality type, its desire/aversion and positive/negative character traits. Designs were created for the lists, which are a reflection of the internal organisation of each personality type. Read about the principles of creating compositions for types in the analysis section.
