ISR-affiliated Professor Ben Shneiderman?s (CS/UMIACS) groundbreaking work in Treemaps is now the subject of an art exhibit at the National Academies Keck Center in Washington, D.C. The exhibit, which opens on Oct. 16, 2014 features 12 works by Shneiderman.
From visually depicting points scored and personal fouls of every player in the NBA to detailing the production output of hundreds of U.S. companies, computer-generated treemaps are a potent tool for taking massive amounts of data and producing a compact roadmap of usable information. Treemaps not only provide a wealth of information for decision-makers worldwide, they?re also attractive to look at.
Shneiderman, a renowned data visualization expert whose work led to Spotfire?s commercial success, pioneered the treemap technique in the early 1990s. Treemaps are used to organize and visualize hierarchical (tree-structured) data as a set of nested rectangles. In this exhibition, he has stripped the text from his treemaps, allowing viewers to consider their aesthetic properties. The featured treemaps are based on data from a range of topics including global population, popular music, carbon emissions, economic growth, popular TED talks, airport activity, and basketball data.
?Although I conceived treemaps for purely functional purposes (understanding the allocation of space on a hard drive), I was always aware that there were aesthetic choices in making appealing treemaps, such as design, color, aspect ratio, and the prominence of borders for each region, each hierarchy level, and the surrounding box. In addition, certain treemaps are inherently interesting because of the data displayed or patterns revealed,? says Shneiderman, who also holds an appointment in the University of Maryland Institute for Advanced Computer Studies. Shneiderman worked closely with Kazi Rahman, ?13, master of information management, to prepare the images and the exhibition catalog.
Shneiderman's artistic influences include the Op art (optical art) movement of the 1960s, as well as the work of Piet Mondrian, Josef Albers, Mark Rothko, Paul Klee, Kenneth Noland, Barnett Newman, and Hans Hofmann.
