Abstract data refers to (heterogenous) data that has no inherent spatial structure; thus it does not allow for a straightforward mapping to any geometry, but relies upon means provided by information visualization for its visual representation.

Therefore creating a virtual reality (VR) is essential to visualizing abstract data. To allow intuitive understanding and to find wide acceptance, virtual spaces will be based on a real–world analogue that mostly supports human cognitive abilities.
