  1. Glyph Visualizationand Yet Another Tree Visualization • Matt Williams • InfoVis 533c • April 3, 2003

  2. Overview • Managing Software with New Visual Representation • TimeWheel • 3D Wheel • InfoBUG • Summary • Intermission • Tree Visualization using SpaceTree • Guiding Principles • Results • Summary

  3. Managing Software with New Visual Representation • Chuah and Eick in Information Visualization Proceedings IEEE 1997. http://www-2.cs.cmu.edu/~mei/infobug.htm • Glyph: A symbol, such as a stylized figure or arrow on a public sign, that imparts information nonverbally. http://www.dictionary.com

  4. Project Management Issues Issues related to large project • Diversity/Variety • Correspondence to real world • Time • Large Data Volumes

  5. Time How can we represent time • Animation? • Good for easily perceived outliers • Time Series Graphs? • Good for comparing across time • TimeWheel Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  6. TimeWheel • Displays trends for a number of attributes at a time • Visually differentiable result comparing increasing vs. decreasing treads • Maintain “Objectedness” through Gestalt principals Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  7. TimeWheel • Can Take it all in one quick look (preattentive pop out??) • Separable (objectedness) • Avoids local grouping effects (closure) Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  8. Time Separable? Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  9. 3D Wheel Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  10. InfoBUG • Show many properties while still maintaining “objectedness” • Certain patterns preattentively pop out • Interactive Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  11. Body • Bar - file changes • Spots – number of subsystems • Useful?? • Tail • Width – new lines (errors/functionality) • Height – Lines deleted InfoBUG • Wings • Lines of Code vs. Number of Errors • Interactive • Head • Code Type Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  12. InfoBUG Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  13. Glyph Visualization • Conclusion • Using gestalt principals Glyphs can objectify properties using and offer trend pattern “pop out” • Questions?? Mei C. Chuah and Stephan G. Eick. Managing software with new visual representations. In Proceedings 97 Information Visualization, pages 30--37. IEEE, 1997. http://citeseer.nj.nec.com/chuah97managing.html

  14. Intermission • Hungry?

  15. Intermission • Suffer! http://www.lardlad.com/cgi-bin/image.cgi?school/school07.gif

  16. Tree Visualization using SpaceTree • Treemaps, Hyperbolic, and now … • SpaceTree • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  17. Tree Visualization using SpaceTree • Navigate by clicking on the nodes • Aggregation of unopened branches into a triangle representing depth and average width. Triangle shading represented number of nodes • Dynamic Filters/Queries • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  18. SpaceTree - Guiding Principles 1) Semantic Zooming vs. Geometric scaling • Simple progressive scaling provides impractical results – must be readable • Instead SpaceTree provides semantic zooming from readable nodes to aggregated triangles • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  19. SpaceTree - Guiding Principles 2) Automatic Maximization the number of levels shown • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  20. SpaceTree - Guiding Principles 3) Decompose the tree animation – Trim, Translate and Grow. • Trim branches that would overlap new branch • Translate Tree so the new branch will fit • Grow Tree 4) Maintain Landmarks to reduce disorientation during animation • Provide Highlight for the chosen node and path to the root • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  21. SpaceTree - Guiding Principles 5) Dynamic filtering/Queries • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  22. SpaceTree - Guiding Principles 6) Data-Aware Zooming Controls • Allow Zooming basing on node selection rather than “free” zooming • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  23. SpaceTree - Results Experiment comparing Windows Explorer, Hyperbolic Browser(Lamping), and SpaceTree. • Node Finding • Returning to previously viewed nodes • Listing ancestors of a node – SpaceTree faster • Find 3 nodes that have more than 10 children – Hyperbolic faster • User Preferences – “coolness factor” • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.

  24. SpaceTree – Summary • Natural, Clear Navigation of Trees • Aggregation – Semantic Zooming • Dynamic Queries • No “Breakthrough” Results • SpaceTree: Supporting Exploration in Large Node Link Tree, Design Evolution and Empirical Evaluation Catherine Plaisant, Jesse Grosjean, and Ben B. Bederson. Proc. InfoVis 2002.
