WikiNodes is an app for the Apple iPad built by IDEA.org. [1] WikiNodes was the first tablet app for browsing Wikipedia using a radial tree approach to visualize how articles and subsections of articles are interrelated. The app displays related items (articles or sections of an article), which spread on the screen, as a spiderweb of icons. [2]
The app uses the SpicyNodes visualization technique which was awarded a "best for teaching and learning" award in 2011 from American Association of School Librarians (AASL), [3] and voted #edchat's 35 Best Web 2.0 Classroom Tools in 2010. [4]
The user interface is based on two display modes:
As of June 2011, the app supports the 36 top Wikipedia languages (by number of articles).
The app was highlighted as a "Staff pick" by Apple's U.S. App Store, Week of May 28, 2011; as "New and Noteworthy" by Apple's U.S. App Store, Week of May 5, 2011; and at other times by Apple's app stores for non-US countries. [10] It has been favorably covered by several bloggers, including those in the references below. [11]

In computing, a visual programming language, also known as diagrammatic programming, graphical programming or block coding, is a programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.
