• Eye-sys / Interactive Data Visualization
• http://www.eye-sys.com/html/gallery.htm Author(s): (unknown) Institution: Interactive Data Visualization (IDV), Inc. Year: 2005 URL: http://www.eye-sys.com/html/gallery.htm Project Description: IDV develops, markets, and licenses visualization software products and tools that deliver enterprise-level benefits to organizations engaged in modeling and simulation, visual simulation, and video game design. One of their tools, called Eye-Sys, is an application designed to quickly gather data from disparate sources, manipulate that data as necessary, and use it to drive interactive, real-time visualizations on consumer-level personal computers. Eye-Sys systems can be conceptualized as a collection of interconnected nodes. Each of these nodes performs computational functions (data input, manipulation, or display) with a collection of internal properties. The nodes can be connected by establishing a directional link from one node property to another. These links establish that one node is transmitting the value of one of its properties into the property of another node. These ?building block? connections define the behavior of the system. Disparate data sources can easily be brought together just by using several input building blocks. For example, ship movements and locations in a spreadsheet can be imported right along with a geographic database that describes the theater of operations. Similarly, various visualization techniques can be brought to bear on incoming data. For example, animated isosurfaces can be used to show real-time radiation levels within a highly detailed rendering of a ship compartment. One of the interesting case studies of Eye-Sys is the Global Cereal Supply Chain (shown here in detail) which maps this global network in quite an enticing way.

• GUESS **
• http://graphexploration.cond.org/ Source: Eythan Adar Category : information visualization tool status : open source / free software packages compatibility : Guess is Jython/Java based. you can construct your own applications and applets without much coding. Summary : GUESS is an exploratory data analysis and visualization tool for graphs and networks. The system contains a domain-specific embedded language called Gython (an extension of Python, or more specifically Jython) which supports the operators and syntactic sugar necessary for working on graph structures in an intuitive manner. An interactive interpreter binds the text that you type in the interpreter to the objects being visualized for more useful integration. GUESS also offers a visualization front end that supports the export of static images and dynamic movies.
example of guess : Netflix Visualization
Author(s): chef-ele Institution: (unknown) Year: 2006 URL: http://www.flickr.com/photos/chef_ele/sets/72157600111346295/ Project Description: As part of the Netflix Prize competition, chef-ele has created a computer algorithm that can show different clusters of movies within the Netflix database. Chef-ele has used the open-source graph visualization package GUESS for most of his visualizations. As he explains: "To generate those graphs I basically calculated the full movie-movie correlation matrix, using a straight Pearson correlation with Fisher confidence interval correction & a few other tweaks. Then my program writes a textfile of node & edge definitions, which GUESS reads in. Each movie is a node in the graph, with a label (movie title). The lines/edges connect each movie with the one most similar neighbor movie (in the Fisher/Pearson sense). (...) The graphs I did make show some very reasonable clusters. Some movies -- especially those in series & sequels -- have stronger / larger clusters (such as Friday the 13th sequels the 'Friends' TV series, everything Star-Trek related, etc). But clusters around 'themes' (kids movies, shoot-em-ups, etc.) were also found by the algorithm & seem pretty clear."
• GVF - The graph visualizatio framework
• http://gvf.sourceforge.net/ Status : Open source The Graph Visualization Framework is a set of design patterns and approaches that can serve as an example for applications that either manipulate graph structures or visualize them. The libraries implement several basic modules for input, graph management, property management, layout, and rendering. Some modules could be made to operate independently with some modification. For example, the graph management module can, in principle, be used as the data structure part of a program which doesn't necessarily use visualization. An application called "Royre" has been built using the GVF. Royre can be altered and extended to fit the needs of users. Some of the rationale for the design is described in a separate PDF document that has been published in Software: Practice & Experience.

Pascal Chirol recognizes there are already plenty of graph-generating tools out there and consequently he questions the value of creating a new one. In his own defense, Pascal doesn't try to simply mimic existing tools, as he introduces some new elements to the mix, and that is always an exercise worth doing. This tool started as a personal interest when Pascal was trying to map the multiple folders and inherent dependencies in his hard drive. The final output, according to the author, represents a continuous workshop, as the architecture of his work, media preferences, and life in general. The abstract visual representation becomes an assembly of Pascal?s small and disjointed elements lost in his machine.

• Improvise **
• http://www.personal.psu.edu/faculty/c/e/cew15/improvise/ Source : Chris Weaver / Geovista center Penn State University Category : information visualization tool status : open source / free software packages Summary : Exploratory visualization based on multiple coordinated views is a rapidly growing area of information visualization. Ideally, users would be able to explore their data by switching freely between building and browsing in a flexible, integrated, interactive graphical environment that requires little or no programming skill to use. However, the possibilities for displaying data across multiple views depends on the flexibility of coordination, the expressiveness of graphical encoding, and the ability of users to comprehend the structure of their visualizations as they work. As a result, exploration has been limited in practice to a small fraction of useful visualizations. Improvise is a fully-implemented Java software architecture and user interface that enables users to build and browse highly-coordinated visualizations interactively. By coupling a shared-object coordination model with a declarative visual query language, users gain precise control over how navigation and selection affects the appearance of data across multiple views, using a potentially infinite number of variations on well-known coordination patterns such as synchronized scrolling, overview+detail, brushing, drill-down, and semantic zoom. Improvise has been used to explore election results, particle trajectories, network loads, music collections, the chemical elements, and even the dynamic coordination structure of its own visualizations in situ. This last technique—integrated metavisualization—is unique to Improvise.
• Info Vis Toolkit
• http://ivtk.sourceforge.net/ Source : Jean-Daniel Fekete Jean-Daniel.Fekete@inria.fr Category : information visualization tool status : open source / free software packages Summary : The InfoVis Toolkit is a Interactive Graphics Toolkit written in Java to ease the development of Information Visualization applications and components. The main characteristics of the InfoVis Toolkit are: Unified data structure (The base data structure is a table of columns. Columns contain objects of homogeneous types, such as integers or strings. Trees and Graphs are derived from Tables) ; Small memory footprint (Using homogeneous columns instead of compound types improves dramatically the memory required to store large tables, trees or graphs, and generally the time to manage them). Unified set of interactive components (Interactive filtering (a.k.a. dynamic queries) can be performed with the same control objects and components regardless of the data structure, simplifying the reuse of existing components and the design of generic ones). Fast (the InfoVis Toolkit can use accelerated graphics provided by Agile2D, an implementations of Java2D based on the OpenGL API for hardware accelerated graphics. On machine with hardware acceleration, some visualizations redisplay 100 times faster than with the standard Java2D implementation). Extensible (the InfoVis Toolkit is meant to incorporate new information visualization techniques and is distributed with the full sources and with a very liberal licence. It could be a base for student projects, reseach projects or commercial products).
• Infovis cyberifrastructure **
• http://iv.slis.indiana.edu/sw/index.html Source : Katy Borner Category : information visualization tool status : open source / free software packages Summary : The Information Visualization CyberInfrastructure (IVC) software framework extends the original Information Visualization Repository (Börner & Zhou, 2001). It is a set of libraries that provide a simple and uniform programming-interface to algorithms and user-interface to end-users by leveraging the power of the Eclipse Rich Client Platform (RCP). While the algorithms might be developed by different researchers and implemented in different programming languages (e.g., Java, Perl, C, C++) using different graphics, math or other packages the IVC framework facilitates the seamless integration of those algorithms into a unified software package. The IVC framework is unique in that it places no restrictions on the type of data structures, algorithms or persistent data formats. By separating out functions such as data load and store, graphical user interface, transaction logging and inter-convertibility between data formats, the IVC lets a programmer concentrate on developing the core code and frees her from issues such as loading the data into the a particular data structure or keeping track of changing results over time.

Category : information visualization tool status : open source / free software packages Summary : Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. By employing a fisheye-like distortion, it provides a display that simultaneously shows local detail and the global context. see more details (+
• Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. It is technically possible to display graphs containing a million nodes or more, but visual clutter, occlusion, and other factors can diminish the effectiveness of Walrus as the number of nodes, or the degree of their connectivity, increases. Thus, in practice, Walrus is best suited to visualizing moderately sized graphs that are nearly trees. A graph with a few hundred thousand nodes and only a slightly greater number of links is likely to be comfortable to work with. Walrus computes its layout based on a user-supplied spanning tree. Because the specifics of the supplied spanning tree greatly affect the resulting display, it is crucial that the user supply a spanning tree that is both meaningful for the underlying data and appropriate for the desired insight. The prominence and orderliness that Walrus gives to the links in the spanning tree, in contrast to all other links, means that an arbitrarily chosen spanning tree may create a misleading or ineffective visualization. Ideally, the input graphs should be inherently hierarchical. Walrus uses 3D hyperbolic geometry to display graphs under a fisheye-like distortion. At any moment, the amount of magnification, and thus the level of visible detail, varies across the display. This allows the user to examine the fine details of a small area while always having a view of the whole graph available as a frame of reference. Graphs are rendered inside a sphere that contains the Euclidean projection of 3D hyperbolic space. Points within the sphere are magnified according to their radial distance from the center. Objects near the center are magnified, while those near the boundary are shrunk. The amount of magnification decreases continuously and at an accelerated rate from the center to the boundary, until objects are reduced to zero size at the latter, which represents infinity. By bringing different parts of a graph to the magnified central region, the user can examine every part of the graph in detail.
