Dynamic graphics for data, means simulating motion or movement using the computer. It may also be thought of as multiple plots linked by time. Two main examples of dynamic graphics are animations, and tours. An animation, very generally defined, may be produced for time-indexed data by showing the plots in time order, for example as generated by an optimization algorithm.
A tour is designed to study the joint distribution of multivariate data, in search of relationships that may involve several variables. It is created by generating a sequence of low-dimensional projections of high-dimensional data – typically 1D or 2D – so that many different aspects of high-dimensional data can be observed. Tours are thus used to find interesting lower-dimensional projections of the data, ideally for data which contains real-valued variables. The data Xn×p is projected into Ap×dto...
