1. XML and Visualization Matthew Burt Megan Kelley

2. Overview A brief introduction to visualization Benefits of XML for visualization Examples and Demos of visualization tools that use XML Questions?

3. What is Visualization? A graphical representation of abstract information structure for human users A new level of presentation for data structures A means for a user to more easily interact with a large amount of information

4. How can Visualization be used? Graphically represent a complex data file, such as an XML file Summarize large amounts of data Interactively present search results Visually show relationships between multiple pieces of information

5. Power of Visualization A new look at information at scale that would be difficult for human to mentally process Presenting data visually sometimes allows for new conclusions upon seeing relationships http://www.commetrix.de/ (Documents/videos – FlashVideo)http://www.commetrix.de/

(2001) Information Management – Topic Maps Visualization, XML Europe 2000, Paris, France “Fundamental factors for a good visualization interface are ( ): An overview of the structure for a global understanding of the structure and of the relationships within the hierarchy, The ability to zoom and to select some nodes, Dynamic requests in order to filter data in real time”

7. Visualizing XML Graphically represent an XML file Search by text and tags Collapse and expand nodes Hydra3d XML visualization tool –http://hydra3d.sourceforge.net/http://hydra3d.sourceforge.net/ LukeLab Noder tool –http://lukelab.com/lab/noder/http://lukelab.com/lab/noder/

8. Benefits of XML for Visualization XML provides tagged data for visualization software XML files can provide a hierarchical arrangement of data XML separates content from presentation
