22nd International Symposium on
Graph Drawing
24—26 September 2014, Würzburg, Germany

21st Graph Drawing Contest

Call for Participation

The 21st Annual Graph Drawing Contest shall be held in conjunction with the 22nd International Symposium on Graph Drawing (GD 2014).

This year, the contest has the three topics: Metro map layout, composers graph, and the graph drawing challenge.

Topic 1: Metro map layout

For this topic, you are given the data of Würzburg's tram and bus network. The data include 25 bus/tram lines with information about their stops as well as geographic information about the stops. The task is to visualize the network in a metro map style layout as clear as possible.

For details, see here.

Topic 2: Composers graph

For this topic, you are given a large directed graph, where the nodes represent Wikipedia articles about composers, and the edges represent links between these articles. The task is to identify the about 150 most important nodes in the graph and to create a layout of the resulting subgraph.

For details, see here.

Topic 3: Graph drawing challenge

The 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 area for orthogonal grid layouts.

For details, see here.

More information about the contest will be available soon!


Electronic submissions (by email) must be received by September 22 (23:59 CEST) and should include the following information:

  • Names and email addresses of the contributors.
  • A picture (or other kind of visualization) illustrating the graph. PDFs are preferred.
  • A brief description on how the graph and layout were produced.

If your drawing requires special printing because of size, resolution, or color constraints, you are encouraged to submit via hard-copy. In this case, please contact us in advance and make sure that your submission is received no later than September 19.
