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. Examples from [[cartography]] include [[Geographia (Ptolemy)|Ptolemy's Geographia]] (2nd century AD), a map of China (1137 AD), and [[Charles Joseph Minard|Minard]]'s map (1861) of [[Napoleon]]'s invasion of Russia a century and a half ago. 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.<ref>{{cite book |last=Tufte |first=Edward R. |author-link=Edward Tufte |year=1990 |title=Envisioning Information|url=https://archive.org/details/envisioninginfor00tuft |url-access=registration |isbn=0961392118}}</ref><ref>{{cite book |last=Tufte |first=Edward R. |author-link=Edward Tufte |edition=2nd |orig-year=1st Pub. 1983 |year=2001 |title=The Visual Display of Quantitative Information |isbn=0961392142 |url=https://archive.org/details/visualdisplayofq00tuft }}</ref><ref>{{cite book |last=Tufte |first=Edward R. |author-link=Edward Tufte |year=1997 |title=Visual Explanations: Images and Quantities, Evidence and Narrative |publisher=Graphics Press |isbn=0961392126 |url=https://archive.org/details/visualexplanatio00tuft }}</ref>
 
Computer graphics has from its beginning been used to study scientific problems. However, in its early days the lack of graphics power often limited its usefulness. The recent emphasis on visualization started in 1987 with the publication of Visualization in Scientific Computing, a special issue of Computer Graphics.<ref>{{cite web|url=http://www.evl.uic.edu/core.php?mod=4&type=3&indi=348|title=evl – electronic visualization laboratory|website=www.evl.uic.edu|access-date=2 September 2018}}</ref> Since then, there have been several conferences and workshops, co-sponsored by the [[IEEE Computer Society]] and [[ACM SIGGRAPH]], devoted to the general topic, and special areas in the field, for example volume visualization.
