A user interface (UI), which reflects exchanges in the past and the future between a user and entities. The UI includes a background having a user defined granularity, a plurality of dots, which can represent at least one collaborative exchange of a user and which are each arranged on the background, a graphic connection between any two or more dots which each represent exchanges between the user and similar entities, a first graphic which includes first level information, and a second graphic which includes second level information. For any set of one or more dots which each represent exchanges between the user and similar entities, the dot closest to or within the central area includes a graphical identifier that indicates whether the entity is currently available for a new exchange.
