(Jack) van Wijk (born 1959) is a Dutch computer scientist, a professor in the Department of Mathematics and Computer Science at the Eindhoven University of Technology, and an expert in information visualization.
His master's thesis, on simulation of traffic collisions, led him to become interested in computer visualization, and he remained at Delft for his doctoral studies, completing a Ph.D. in 1986 under the supervision of Dennis J.
[2][3] He worked at the Energy Research Centre of the Netherlands from 1988 until 1998, when he joined the Eindhoven faculty; he was promoted to a full professorship in 2001.
[2] As well as being a faculty member at TU Eindhoven, van Wijk is the vice president for scientific affairs at MagnaView, a Dutch information visualization company.
[14] He has also conducted user studies that showed that the standard depiction of directed edges in graph drawings using arrowheads is less effective at conveying the directionality of the edges to readers than other conventions such as tapering.
