Charles Minard's information graphic of Napoleon's march The use of visualization to present information is not a new phenomenon. It has been used in maps, scientific drawings, and data plots for over a thousand years.
Most of the concepts learned in devising these images carry over in a straightforward manner to computer visualization. Edward Tufte has written three critically acclaimed books that explain many of these principles.
However, in its early days the lack of graphics power often limited its usefulness.
The recent emphasis on visualization started in with the publication of Visualization in Scientific Computing, a special issue of Computer Graphics.
Most people are familiar with the digital animations produced to present meteorological data during weather reports on televisionthough few can distinguish between those models of reality and the satellite photos that are also shown on such programs.
TV also offers scientific visualizations when it shows computer drawn and animated reconstructions of road or airplane accidents. Some of the most popular examples of scientific visualizations are computer-generated images that show real spacecraft in action, out in the void far beyond Earth, or on other planets.
Apart from the distinction between interactive visualizations and animation, the most useful categorization is probably between abstract and model-based scientific visualizations.
Computer graphics is the field that deals with display and control of images on the computer screen. Applications may be broken down into four major categories: (1) design (computer-aided design [CAD] systems), in which the computer is used as a tool in designing. Visualization today has ever-expanding applications in science, education, engineering (e.g., product visualization), interactive multimedia, medicine, etc. Typical of a visualization application is the field of computer graphics. IEEE Transactions on Visualization and Computer Graphics (TVCG) publishes papers on subjects related to computer graphics and visualization techniques, systems, software, hardware, and user interface issues. Specific topics in .
The abstract visualizations show completely conceptual constructs in 2D or 3D. These generated shapes are completely arbitrary. The model-based visualizations either place overlays of data on real or digitally constructed images of reality or make a digital construction of a real object directly from the scientific data.
Scientific visualization is usually done with specialized softwarethough there are a few exceptions, noted below.
Some of these specialized programs have been released as open source software, having very often its origins in universities, within an academic environment where sharing software tools and giving access to the source code is common. There are also many proprietary software packages of scientific visualization tools.Some topics in computer graphics include user interface design, sprite graphics, vector graphics, 3D modeling, shaders, GPU design, implicit surface visualization with ray tracing, and computer vision, among others.
Computer graphics are pictures and films created using computers. Usually, the term refers to computer-generated image data created with the help of specialized graphical hardware and software. Prospective students who searched for List of the Best Computer Graphics Schools and Colleges in the U.S.

Rapid advances in 3-D scientific visualization have made a major impact on the display of behavior. The use of 3-D has become a key component of both academic research and commercial product development in the field of engineering design.
