Walrus - Graph Visualization Tool

Walrus - Graph Visualization Tool
Source Code Available The source code to Walrus is now available under the GNU GPL. You may download the source code below. Description Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. Walrus computes its layout based on a user-supplied spanning tree. Walrus uses 3D hyperbolic geometry to display graphs under a fisheye-like distortion. Walrus is being developed by Young Hyun at CAIDA. Applicability Please note that Walrus currently has the following requirements, restrictions, or limitations which may render it unsuitable for a given problem domain or dataset: Only directed graphs are supported.Only connected graphs with reachable nodes are supported. Galleries The following galleries show graphs of various sizes and complexity. Implemented Features Features Under Consideration more options for coloring objects (such as with a perceptually uniform colorscale)filtering and other interactive processing Requirements Download Changes References

Revised Graphic Organizers Make Mapping Out Ideas Easy—and Savable! Join us on Facebook to get the latest news and updates. Become a Fan ReadWriteThink couldn't publish all of this great content without literacy experts to write and review for us. More Home › About Us › News News | August 17, 2011 Recently revised, three online interactive graphic organizers help students map out their writing ideas or organize information they have learned. Try the new save capability with your students using any one of these interactive mapping tools. Students often have trouble getting started when asked to write an essay. You can’t compare apples to oranges. Still need some convincing? For a short tutorial on how to use the new save capability in select Student Interactives, see ReadWriteThink ReView: Saving Work With the Student Interactives.

D veloppement avanc avec Eclipse Zest Dans l'article précédent, Introduction à ZestIntroduction à Zest, nous avons vu comment construire un graphe, que ce soit à partir d'un modèle en utilisant les mêmes mécanismes que JFace, ou directement en créant nœuds et branches. Cet article reprend l'exemple de l'article précédent, et se propose de montrer comment enrichir le graphe de diverses manières : soit par le biais de styles personnalisés, de menus contextuels, ou encore par la mise en place d'un zoom, ou de layouts différents. Ce tutoriel suppose que vous disposiez des connaissances de base sur les technologies suivantes : Par ailleurs, nous repartons sur le graphe orienté "branches" de l'article d'introduction, contenu dans la vue "LinkView". Les sources sont disponibles ici (FTP)src-intro-ftp ou ici (HTTP)src-intro-http. La boîte à outils Zest possède plusieurs algorithmes d'agencement pour un graphe, qui modifient la disposition initiale du graphe lors de sa construction. Sélectionnez

You may download LibSea from either libsea-0.1-src.tar.gz or A precompiled jar file is distributed with the Walrus graph visualization tool. About the LibSea Graph File Format The LibSea file format allows you to specify the topology of directed graphs using nodes, links, and paths (paths are sequences of links)attach data to nodes, links, and paths in a flexible mannerimplement application-specific conventions and semantics Users can attach data to topological elements (nodes, links, and paths) using attributes. LibSea graph files can also contain qualifiers. For example, there is no direct method of specifying a spanning tree in a LibSea graph file, but this can be easily accomplished with a qualifier. LibSea Java Graph Library It is relatively easy to design a data structure that can compactly represent the topology of graphs, even graphs with millions of nodes. Applicability

Infographics news The Draw2d Examples - A Hidden Treasure While this is not really documented, hidden in the depths of the GEF cvs repository, there is quite a bunch of nice little Draw2d examples, which may help beginners as well as prospective experts in understanding the framework's principles and mechanisms. All that has to be done in order to access them is to check out the org.eclipse.draw2d.examples plug-in from the examples module of the repository (please follow GEF's getting involved pages for detailed instructions on how to access the repository). All examples are implemented as standalone Java applications, so they can quite easily be executed. Of course, every set of examples has to include a "Hello World". But there's more. And what about playing around a bit with shape styles... ... or learning more about the behavior of locators? There's also something to demonstrate Draw2d's more advanced features like shortest path connection routing ... ... directed graph layout ... ... zooming ... ... printing ... ... or text flows.

Information design Information design is the practice of presenting information in a way that fosters efficient and effective understanding of it. The term has come to be used specifically for graphic design for displaying information effectively, rather than just attractively or for artistic expression. Information design is closely related to the field of data visualization and is often taught as part of graphic design courses.[1] Etymology[edit] The term 'information design' emerged as a multidisciplinary area of study in the 1970s. In 1982, Edward Tufte produced a book on information design called The Visual Display of Quantitative Information. The term information graphics tends to be used by those primarily concerned with diagramming and display of quantitative information. In technical communication, information design refers to creating an information structure for a set of information aimed at specified audiences. Early examples[edit] Applications[edit] See also[edit] References[edit]

Information graphics Information graphics or infographics are graphic visual representations of information, data or knowledge intended to present complex information quickly and clearly.[1][2] They can improve cognition by utilizing graphics to enhance the human visual system’s ability to see patterns and trends.[3][4] The process of creating infographics can be referred to as data visualization, information design, or information architecture.[2] Overview[edit] Infographics have been around for many years and recently the proliferation of a number of easy-to-use, free tools have made the creation of infographics available to a large segment of the population. Social media sites such as Facebook and Twitter have also allowed for individual infographics to be spread among many people around the world. In newspapers, infographics are commonly used to show the weather, as well as maps, site plans, and graphs for statistical data. "Graphical displays should: Graphics reveal data.
