23rd International Symposium on
Graph Drawing & Network Visualization
September 24-26, 2015, Los Angeles, CA, USA

22nd Graph Drawing Contest

Call for Participation

The 22nd Annual Graph Drawing Contest shall be held in conjunction with the 23rd International Symposium on Graph Drawing and network Visualization (GD 2015).

The contest has two parts: the Creative Topics and the Live Challenge.

Creative Topics

The creative topics are provided several months before the conference and focus on free-form visualisation of specific graphs. Two graphs are provided, and participants are invited to submit any drawings of one or both of the graphs. The submissions will be judged by the contest committee during the symposium. This year's topics are the graph of graph classes, and the Tic Tac Toe game graph.

For details, see here.

Live Challenge

The live challenge will be held during the conference in a format similar to a typical programming contest, where 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.

For details, see here.

  • Creative Topics: Graph Classes
  • Creative Topics: Tic Tac Toe
  • Live Challenge: Automatic Category
  • Live Challenge: Manual Category
