Joint Proceedings of
4th International Workshop on Euler Diagrams
and the
1st International Workshop on Graph
Visualization in Practice
In 2014 two workshops ran alongside the Diagrams conference, held that
year in Melbourne, Australia. These were the 4th International Workshop on
Euler Diagrams (ED2014) and the 1st International Workshop on Graph Visu-
alization in Practice (GraphViP2014). The complementary scopes of the events
prompted the organisers to issue a joint proceedings.
Euler Diagrams
Euler diagrams have become the foundation of various visual languages and
have facilitated the modelling of, and logical reasoning about, diverse complex
systems. Over the years, they have been extensively used in areas such as
biosciences, business, criminology and national security to intuitively visualize
relationships and relative cardinalities of sets. This workshop of peer-reviewed
submissions gave the growing Euler diagrams community the opportunity to
present and discuss new research, and to share multi-interdisciplinary expertise.
This was the second time the workshop has run as part of the Diagrams confer-
ence series and follows on from successful workshops in 2012, 2005 and 2004. It
was an event which brought together researchers from both academia and indus-
try, including those with expertise in mathematics, computer science, artificial
intelligence, information design, visualization, human-computer interaction, as
well as end-users from various application areas.
Each submission to ED2014 was reviewed by at least two members of the
Program Committee, which was made up of the following expert researchers:
• Francesco Bellucci (Tallinn University of Technology),
• Peter Chapman (University of Brighton),
• Rosario de Chiara (Poste Italiane),

• Renata de Freitas (Universidade Federal Fluminense),
• Tim Dwyer (Monash University),
• Jean Flower (Autodesk),
• Mateja Jamnik (University of Cambridge),
• Luana Micallef (University of Kent),
• Mitsuhiro Okada (Keio University),
• Peter Rodgers (University of Kent),
• Frank Ruskey (University of Victoria), and
• Sun-Joo Shin (Yale University).
We are indebted to the Program Committee for helping to make ED2014 a
success, and to our keynote speaker, Professor Atsushi Shimojima, whose work is
seminal in the diagrams field. Professor Shimojima spoke on Euler diagrams as
“Single Feature Indicator Systems” (SFISs), using an analytical method which
identifies the affordances Euler diagrams have in common with other SFISs,
such as railway timetables.
Graph Visualization in Practice
Graphs provide a versatile model for data from a large variety of application
domains, including biology, finance, information security, telecommunication,
software engineering, and social sciences. Graph visualization helps scientists
and engineers to understand critical issues in these domains. However, the depth
of understanding depends on the quality of the visualization and the interactive
interface. Graph visualization techniques need to be intuitive for domain experts
to facilitate exploration of networks within the expert’s work flow, and have to
take into account application semantics or user-defined constraints.
This workshop provided the graph visualization community a forum to ex-
change and discuss challenges, trends, and experiences in practical graph visu-
alization. It was the first time such a workshop was held, and we expect that
this event can be established in the future not only to discuss challenges and
advances in research, but to further investigate how to facilitate the transfer of
research results into practical applications.
Each submission to GraphViP2014 was reviewed by at least two members
of the Program Committee, which consisted of the following expert researchers:
• Markus Chimani (Osnabrück University)
• Walter Didimo (University of Perugia)
• Carsten Gutwenger (Technical University Dortmund)

• Yifan Hu (Yahoo Labs)
• Ilir Jusufi (University of California Davis)
• Quang Vinh Nguyen (University of Western Sydney)
• Martin Nöllenburg (Karlsruhe Institute of Technology)
• Petr Novak (Institute of Plant Molecular Biology, Ceske Budejovice)
• Michael Wybrow (Monash University, Melbourne)
We are grateful to all members of the Program Committee and all authors
for their excellent work. We would like to thank the invited speakers Tim
Dwyer, Tim Pattison, and Falk Schreiber, for their very interesting talks that
provided the audience insight into quite different areas of application: Tim
Dwyer shared his experience in building a useful software dependency visualiza-
tion tool, CodeMaps, Tim Pattison presented an approach for the interactive
visualization of formal concept lattices, and Falk Schreiber gave a survey on cur-
rent approaches and challenges in biological network visualization. Our thanks
equally go to the Organizing Committee for the local arrangements.
