well, data representations can be of many types wich can be outputted from a computer like:
1.) Graphical: By use of graphs (bar graphs, line graphs etc.) , pie charts.
2.) Geometric: By use of base plots, scatter diagrams etc.
3.) Icon based: by use of icons to represent various o/p levels.
4.) Colour based: using different colors -------ditto----------.
5.) Pixel based: using various pixels--------ditto-------------.
6.) hierarchical: shading the area based on diff o/p levels.
but always remember buddy, that a computer can o/p any of the 4 multimedia components wich are text, picture, audio, video i guess nothing more than that as these are the basic and core components of a multimedia system a.k.a computer system.
