GUESS: The Graph Exploration System Interactive Dynamics for Visual Analysis Graphics Jeffrey Heer, Stanford University Ben Shneiderman, University of Maryland, College Park The increasing scale and availability of digital data provides an extraordinary resource for informing public policy, scientific discovery, business strategy, and even our personal lives. To get the most out of such data, however, users must be able to make sense of it: to pursue questions, uncover patterns of interest, and identify (and potentially correct) errors. In concert with data-management systems and statistical algorithms, analysis requires contextualized human judgments regarding the domain-specific significance of the clusters, trends, and outliers discovered in data. Visualization provides a powerful means of making sense of data. The goal of this article is to assist designers, researchers, professional analysts, procurement officers, educators, and students in evaluating and creating visual analysis tools. Some visualization system designers have explored alternative approaches.
NodeXL: Network Overview, Discovery and Exploration for Excel - Home Gephi, an open source graph visualization and manipulation software Data Visualization Software | Tulip Navicrawler | WebAtlas UPDATE: There now a portable version of Firefox with Navicrawler included: More information on these: These folders are zipped. Unzip and run “Firefox Portable”. You might have some obvious messages, and after that you have a fully functionnal Firefox 3.6 with Navicrawler installed.These are portable apps, it means that they do not interfere with other versions of Firefox that you might have. They do not install, you have to run them from their folder.Two other extensions are also installed: Flem and Greasemonkey. Regular versions: You can download the Navicrawler 1.7 or the Navicrawler 1.8b (now hosted directly on WebAtlas.fr). The Navicrawler is no longer supported. In this “next generation Navicrawler” you will be able to dynamically change the boundaries of every website, to have graphs with pages and websites at the same time, and to declare aliases (the same website with different domain names).

Fast Thinking and Slow Thinking Visualisation Last week I attended the Association of American Geographers Annual Conference and heard a talk by Robert Groves, Director of the US Census Bureau. Aside the impressiveness of the bureau’s work I was struck by how Groves conceived of visualisations as requiring either fast thinking or slow thinking. Fast thinking data visualisations offer a clear message without the need for the viewer to spend more than a few seconds exploring them. These tend to be much simpler in appearance, such as my map of the distance that London Underground trains travel during rush hour. The explicit message of this map is that surprisingly large distances are covered across the network and that the Central Line rolling stock travels furthest. It is up to the reader to work out why this may be the case. or the seemingly impenetrable (from a distance at least), but wonderfully intricate hand drawn work of Steven Walter (click image for interactive version).
Quelques outils pour visualiser les réseaux sociaux L’analyse des réseaux sociaux permet de mieux comprendre le comportement des acteurs et des communautés : quelle est la place de l’acteur au sein de l’ensemble ? Est-il central ? périphérique ? Cette analyse permet de comprendre en profondeur le fonctionnement des communautés en ligne. L’analyse des réseaux sociaux se fait en trois temps distincts : la récupération des données, leur analyse et leur visualisation. Sur de petits graphes, il est possible de faire la récupération des données a la main. Les données qui sont récupérées concernent le lien : qui est lié à qui ou à quoi, mais on pourra également s’intéresser au volume d’information produits, à sa fréquence et faire quelques corrélations. Navicrawler est une extension Firefox qui explore le contenu et la structure des pages web. Navicrawler n’assurant que la récolte des données, leur traitement doit se faire avec un autre programme : Pajek, Guess, Network Workbench Tool, ou NodeXL.
