Graph drawing is concerned with the theory of and algorithms for thegeometric representation of graphs,while network visualization has wideapplicationsinunderstandingandanalyzingrelationaldatasets.Informationabout theconferenceseriesandpastsymposiaismaintainedathttp://www.graphdrawing.org. Thisyear,theconferencewashostedbytheInstituteofCommunicationsandComputer Systems, an affiliate of the National Technical University of Athens, with Antonios SymvonisasthechairoftheOrganizingCommittee.Atotalof99participantsfrom16 countries attended the conference, whose venue was located in the beautiful historic center of Athens. Papersubmissionsweredividedintotwomaintracksandanadditionalpostertrack: Track 1 for combinatorial and algorithmic aspects of graph drawing and Track 2 for experimental, applied, and network visualization aspects. In each of the two tracks authors could submit full papers or short papers. All tracks were handled by a single Program Committee. In response to the call for papers, the Program Committee received a total of 112 submissions consisting of 99 papers (66 in Track 1 and 33 in Track 2)and13posters. More than 350 expert reviews were provided, ofwhichmore than 130 were contributed by external subreviewers. After often extensive electronic discussions,theProgramCommitteeselected44papersandall13postersforinclusion inthescientificprogramofGD2016.Thisresultedinanoverallpaperacceptancerate of44%(48%inTrack1and36%inTrack2).Twonewpolicieswereintroducedinthe submissionandpublicationprocessthisyear.Firstly,referencesnolongercounttoward thepagelimitsof12pagesforregularpapersandsixpagesforshortpapers.Secondly, electronic versions of all accepted papers were made available through a conference index on the ArXiv repository before the conference. There were two keynote talks at GD 2016. Roger Wattenhofer (ETH Zurich, Switzerland) talked about “Distributed Computing: Graph Drawing Unplugged” and Daniel Keim (University of Konstanz, Germany) talked about “The Role of Visual Analytics in Exploring Graph Data.” Abstracts of both talks are included in the proceedings. SpringersponsoredawardsforthebestpaperineachofTrack1andTrack2,plusa bestpresentationawardandabestposteraward.TheProgramCommitteevotedtogive the best paper award in Track 1 to the paper “Block Crossings in Storyline Visual- izations” by Thomas C. van Dijk, Martin Fink, Norbert Fischer, Fabian Lipp, Peter Markfelder, Alex Ravsky, Subhash Suri, and Alexander Wolff, and in Track 2 to the paper“ASparseStressModel”byMarkOrtmann,MirzaKlimenta,andUlrikBrandes. The participants of the conference voted to give the best presentation award to Martin Gronemann for his presentation of the paper “Bitonic st-orderings for Upward Planar Graphs” and the best poster award to Jonathan Klawitter and Tamara Mchedlidze for VI Preface their poster entitled “Heuristic Picker for Book Drawings.” Congratulations to all award winners for their excellent contributions! Following the tradition, the 23rd Annual Graph Drawing Contest was held during the conference. The contest had two parts, each with two categories: the Creative Topics (Panama papers and Greek mythology family tree) and the Live Challenge on crossing minimization in book embeddings (Automatic Category and Manual Cate- gory). Awards were given in each of the four categories. We thank the Contest Committee for preparing interesting and challenging contest problems. A report about the contest is included in the proceedings. Directly after GD 2016, a two-day PhD school on “Visualization Software” took place. We thank Antonios Symvonis for organizing this satellite event. A short report about the school is also included in the proceedings. Many people and organizations contributed to the success of GD 2016. We thank the Program Committee members and the external reviewers for carefully reviewing and discussing thesubmitted papers and posters,and for putting together a strong and interestingprogram.ThankstoalltheauthorsforchoosingGD2016asthepublication venue for their research. Further, we thank the local organizers, Kostas Karpouzis, ChrysanthiRaftopoulou,AntoniosSymvonis,andIoannisTollis,andallthevolunteers who put a lot of time and effort into the organization of GD 2016. GD 2016 thanks its sponsors, “gold” sponsor Tom Sawyer Software, “silver” sponsors yWorks and Microsoft, and “bronze” sponsor Springer. Their generous supporthelps toensure thecontinuedsuccessofthisconference.Wefurther thankthe team behind EasyChair for providing an incredibly useful conference management system.
