ABSTRACT
Visualization is the graphical presentation of information, with the goal of providing the viewer with a qualitative understanding of the information contents. Information can be in any form, like data, processes, relations, or concepts. Graphical presentation may entail manipulation of graphical entities (points, lines, shapes, images, text) and attributes (color, size, position, shape). Understanding of information involves detection, measurement, and comparison. It can be further enhanced via interactive techniques and providing the information from multiple views and with multiple techniques.
One of the active research and challenging task is representing and making sense of multidimensional data, partially due to the three- dimensional space we live in. Visualization techniques are powerful sense-making tools that support knowledge workers in their decision-making activities by stimulating visual thinking. While most of the scientific, engineering, and business data is multi-dimensional; i.e. datasets contain typically more than three attributes of data.
