The 14th International Symposium on Graph Drawing (GD 2006) was held in Karlsruhe, Germany, during September 17-20, 2006. The conference attracted 108 participants from 18 countries. In response to the call for papers, the Program Committee received 91 s- missions by (co)-authors from 31 countries. At least three Program Committee members reviewed each submission, and after an intensive evaluation phase, the Program Committee selected 33 long papers, 5 short papers, as well as one s- tem demo and 3 posters. The authors receivedextensive comments and excerpts from the discussion on their papers. The best paper award went to Jan Arne Telle and David R. Wood for their paper with the title “Planar Decompositions and the Crossing Number of Graphs with an Excluded Minor. ” The Chairs of the conference invited two distinguished lecturers: Emo Welzl from the ETH in Zur ¨ ich gave a very nice and inspiring presentation on “The Number of Crossing-Free Con?gurations in Planar Point-Sets. ” Oliver Deussen fromthe Universit¨ atKonstanztalkedabout“TheAlgorithmicBeautyofVirtual Nature. ” Abstracts of the two invited lectures can also be found in this volume. An ambitious graph drawing contest took place this year under the guidance of Christian Duncan, who also included a report in this volume. In the so- ware exhibition the industrial sponsors of the conference, Tom Sawyer Software, yWorks GmbH and ILOG Inc. , had the chance to provide a closer look at the products and developments.
