All data for next year's Creative Topics are now available online! The topics were already announced at this year's symposium: a small graph of Graph Drawing citations, and a large graph encoding the human metabolism - the largest manually drawn hypergraph in biology that we are aware of.

The winning submission of the Creative Topics: Greek Mythology. The graph, drawn by Jonathan Klawitter and Tamara Mchedlidze from Karlsruhe Institute of Technology, shows the family "tree" of popular characters from Greek mythology. A vector-based version of the drawing, as well as the topic description and other submissions, can be found on www.graphdrawing.de/contest2016/results.html.

The website for the 2016 GD Contest is now online!

We have two nice creative topics this year. The first graph represents relations between countries through off-shore companies, as recently revealed in the so-called "Panama papers". The second graph is a family tree of the most popular (according to the internet) ancient Greek gods. On top of that, there will again be a live challenge during the conference in September!

The winning submission of the Creative Topics: Tic-Tac-Toe category. The graph, drawn by Jennifer Hood and Pat Morin from Carleton University, shows the possible transitions among (classes of symmetric) board positions in the game Tic-Tac-Toe. A vector-based version of the graph can be found on www.graphdrawing.de/contest2015/results.html.

The Graph Drawing Challenge 2015 will take place today! We hope you are all excited and ready to draw some beautiful graphs. For those who plan to participate remotely, please note that the challenge takes place from 6 pm to 7 pm local time in Los Angeles, which is Pacific Daylight Time (and not Pacific Standard Time as was written in some earlier announcements).

Dear Graph Drawers,

The 2015 Graph Drawing Challenge is about to take place in just over a week! Here is some practical information for those of you who wish to participate.

If you are attending the Graph Drawing Symposium, you can choose to participate in either the manual or automatic category. In either case, you will need to bring an internet-enabled laptop or other device to the conference. If you wish to participate in the manual category, you will need to have java 8 installed on your laptop, and you can attempt to solve the problems using a supplied tool. You can already download the tool and familiarize yourself with its use here:

www.graphdrawing.de/tools/bookembed.jar

If you wish to participate in the automatic category, you can use any software you wish to solve the problems, including the supplied tool (however, problems instances will be much larger than in the manual category).

If you are not attending the symposium, you can still participate remotely in the automatic category.

This year, the challenge will be run through an online submission system. This system is experimental, and we will still allow submission by usb (if you are attending the symposium) or by e-mail (if you are not attending the symposium - in this case the e-mail should arrive before the end of the contest). However, submission through the system is recommended. You can already visit the system and try out some test graphs here:

We hope to see you all at the challenge, and good luck!

Dear Graph Drawers & Network Visualizers!
 
As you know, the 23rd International Symposium on Graph Drawing and Network Visualization will take place in Los Angeles, CA, from September 24 to 26, 2015. As has been tradition since 1994, the symposium will be accompanied by a Graph Drawing Contest, allowing all community members to demonstrate their graph drawing skills in a fun competitive setting. I am pleased to announce the contents of this year's contest.
 
Creative Topics
 
For your entertainment and inspiration, we have composed two nice graphs that you may draw with full artistic freedom. The first, smaller, graph represents inclusion relations of several graph classes. The second, larger, graph represents all possible game states of the game Tic Tac Toe. In both cases, you may visualize the graph in any way you like. Submissions will be judged both on aesthetic appeal and clarity of displayed structure and information. For more details, visit http://www.csun.edu/gd2015/topics.htm
 
Live Challenge
 
Following popular tradition, a live challenge will be held during the symposium in a format similar to a typical programming contest. Teams are presented with a collection of challenge graphs and have approximately one hour to submit their highest scoring drawings. This year, the challenge shall focus on minimizing the crossing number in book embeddings. Teams may either draw the graphs manually, or use their own customized tools. Remote participation will also be possible. For more details, visit http://www.csun.edu/gd2015/challenge.htm
 
Awards
 
Thanks to our generous sponsors, a $200 prize will be awarded to the winner or winning team in four different categories.
 
Looking forward to your submissions!
