  1. Visualization of DMM using GraphVis and WebDot Timothy C. Lethbridge SITE, University. of Ottawa tcl@site.uottawa.ca

  2. Our goals • Solve SORTIE assigned problems • Experiment with lightweight, reusable components for building reverse engineering tools Timothy C. Lethbridge

  3. Timothy C. Lethbridge

  4. Next slides show XSL and generated GraphVis /WebDot input • XSL used to translate from GXL/DMM • Output form is .dot Timothy C. Lethbridge
