"The purpose of visualization is insight, not pictures" - Ben Shneiderman (1999) Over the past few months I've been talking with many people passionate about Information Visualization who share a sense of saturation over a growing number of frivolous projects. The criticism is slightly different from person to person, but it usually goes along these lines: "It's just visualization for the sake of visualization", "It's just eye-candy", "They all look the same". When Martin Wattenberg and Fernanda Viégas wrote about Vernacular Visualization, in their excellent article on the July-August 2008 edition of interactions magazine, they observed how the last couple of years have witnessed the tipping point of a field that used to be locked away in its academic vault, far from the public eye.
Protovis. Protovis composes custom views of data with simple marks such as bars and dots.
Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.

Swayne, Michael L. Littman, Nathaniel Dean From 1991 to 1996, there was a spate of development and public distribution of highly interactive systems for data analysis and visualization, e.g., XGobi, ViSta by Deborah Swayne, Di Cook, Andreas Buja, and Forrest Young (1940-2006). Google Ngram Viewer. CiteSpace: visualizing patterns and trends in scientific literature. CiteSpace is a freely available Java application for visualizing and analyzing trends and patterns in scientific literature.
It is designed as a tool for progressive knowledge domain visualization (Chen, 2004). It focuses on finding critical points in the development of a field or a domain, especially intellectual turning points and pivotal points. Detailed case studies are given in (Chen, 2006) and other publications. CiteSpace provides various functions to facilitate the understanding and interpretation of network patterns and historical patterns, including identifying the fast-growth topical areas, finding citation hotspots in the land of publications, decomposing a network into clusters, automatic labeling clusters with terms from citing articles, geospatial patterns of collaboration, and unique areas of international collaboration.
