the 30th International Symposium on Graph Drawing and Network
Visualization will take (hopefully) place in Tokyo, Japan, from
September 13 to 16, 2022. 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. Due to the uncertainty regarding future travel and
physical meeting restrictions caused by the Corona virus outbreak, the
contest will be either held completely online or in a hybrid format.
Details of the exact format of the contest will be announced around the
Graph Drawing submission deadline. The contest has two parts: the
Creative Topics and the Live Challenge.
1) Live Challenge
Following popular tradition, a live challenge will be held the day
before 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 focuses on
minimizing the planar polyline edge-length ratio on a fixed grid.
Teams may either draw the graphs manually (manual category), or use
their own customized tools (automatic category). Remote participation
will be possible for both the manual and the automatic category.
The live challenge will take place during the conference.
To solve the instances and submit your solutions, you will be provided
with a dedicated tool:

Note that the target function changed slightly compared to last year,
but the tool has not been updated yet for the new function.

2) Creative Topics
For your entertainment and inspiration, we have composed two nice graphs
that you may draw with full artistic freedom.
1. Opera Network
The data represents a collection of opera performances that took place
across Europe between 1775 and 1833. The data was extracted from the
RISM database (https://opac.rism.info/main-menu-/kachelmenu/data) and
was offered by Frans Wiering - professor of Utrecht University studing
Musicology. There are several possibilities on how a network can be
extracted from this data. We leave it to the participants to decide how
and whether to model this data set as a network.
2. Aesthetic Experience Network
The data set represents 8 networks that model an aesthetic experience of
the viewers when observing artworks. The analyzed artworks are 8
paintings by Klee, Kandinsky, Mortensen, Miro and Winter. Each of the 14
nodes represents one of the two polarities of an aesthetic effect, and
the edges are weighted by conditional dependence relations among
aesthetic effects.
In both cases, you may visualize the graph in any way you like.
Submissions will be judged on a list of criteria that includes, but is
not limited to, readability, aesthetics, novelty, and design quality.
The weighting of the criteria might be different for the two graphs.
Submissions will be handled through EasyChair.

Submission deadline: September 05 (23:59 PDT)
3) Awards
We are hoping to be able to award a monetary prize to up to three
submissions in each of the four different categories. Details will follow.
We are looking forward to your submissions!
Best regards,
the Graph Drawing Contest Committee,
Philipp Kindermann, Tamara Mchedlidze, and Wouter Meulemans
