Title 2D Representation
Context

There are a number of data items, from one or more datasets, that need to be viewed by the user.
Problem

How to represent the data in visual form?
Forces
  • The number of data items is relatively low.
  • The structure of the data or the source from which it was gathered does not require the use of the third dimension.
  • The dimensionality of the data is such that it does not warrant the use of the third dimension.
    • Solution

    Use a 2D representation.

    If the quantity of data items is relatively low, or the number of data dimensions that need to be displayed simultaneously can easily be incorporated into one or more views, or if the data fits naturally into a 2D space, then a 2D representation may be appropriate.

    2D representations have a number of advantages over 3D representations. In particular comparison and selection of individual data items is often much easier, navigation models are easier to use and implement, depth cues are not necessary, etc.
