24th International Symposium on
Graph Drawing & Network Visualization
19-21 September 2016, Athens, Greece

Graph Drawing Creative Topics


We have two creative topics, that are judged independently:

  • Panama papers: This graph models the relations between countries through off-shore companies as revealed by the so-called "Panama papers".
  • Greek Mythology: This graph is a famility "tree" of the most popular persons in ancient greek mythology.

Participants may submit drawings of both graphs (or only one graph).

Panama Papers

The International Consortium of Investigative Journalists (ICIJ) is a global network of more than 190 investigative journalists in more than 65 countries who collaborate on in-depth investigative stories. Recently, the ICIJ released an Offshore Leaks Database of almost 320,000 offshore companies and trusts from the Panama papers and the Offshore Leaks investigations.

For the first creative topic, we processed the database to create a weighted directed graph that shows the relationships between countries. A directed edge from country A to country B with weight w means that there are w Offshore Entities in country B that are linked to a company in country A.

The format of the graph is as follows: For each country with offshore entities, an adjacency of its incoming edges together with their weight is given in the following way:

Target1: {
	Source1: weight1
	Source2: weight2

The resulting layout of the graph should contain the names of the countries and should give a good overview on their correlation.

The graph is available here.

Greek Mythology

The following data comes from the Greek Mythic Genealogy Project.

Greek myth contains a large amount of genealogical information. Various characters are related to each other in ways that are difficult for the non-specialist to keep track of, if for no other reason than that there are such a large number of gods, heroes, and other characters who appear in the various myths, epics, lyrics, legends, comedies, and other material. The Greek Mythic Genealogy Project is a fragmentary attempt to keep track of some of these relationships.

For the second creative topic, you are asked to draw a family "tree" of popular persons in Greek Mythology. We created a subgraph of the large database by extracting only the most popular (by the number of Google results) names and their parents. This reduced the number of nodes to 118. The data is provided in csv format with one row per person and the following five attributes:

  1. NAME: The name of the person
  2. FATHER: The name of the person's father
  3. MOTHER: The name of the person's mother
  4. SEX: The sex of the person
  5. POPULARITY: the number of Google results for the person's name

The task is to provide a nice visualization of the family tree based on the given information.

The graph is available here.


For the creative topics, you are completely free to use any drawing style you wish. Your submissions will be judged both on aesthetic value and on the clarity of information displayed.


Electronic submissions (by email) must be received by September 11 (23:59 CEST) and should include the following information:

  • Names and email addresses of the contributors.
  • A visualization illustrating the graph in a format of your choosing.
  • A brief description on how the graph and layout were produced.
  • A web-friendly image of your visualization. Max resolution 1000 by 1000 pixels.
  • A pdf version of your visualization, suitable for printing on a large A0 poster.

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 4.
