The term "visualisation" refers to the graphical representation of data or relationships provided by a database. It is used for controlling and monitoring automated machines and systems (also see communications system).
Electronic displays (such as monitors or graphic displays) are used to represent the information. This means, for example, that machine operator stations can take the form of text/graphical displays or PC-based solutions.
Within the context of flow process experiments, the flow can be visualised by adding dyestuffs or tracer particles to the fluid.
