They then begin volleying a ball back and forth across a graphical representation of a net.

In this graphical representation of reflective sampling, the shape indicates the bounds of a sampling slice.

A graphical representation relates the various subsystems or parts of a system through functions, data, or interfaces.

Unit quaternions, while computationally convenient, do not lend themselves to graphical representation because of their four-dimensional nature.

In order to calculate with vectors, the graphical representation may be too cumbersome.
