The 3rd International Workshop on Euler Diagrams (Euler Diagrams 2012) was
held in Canterbury, UK on 2nd July 2012 in conjunction with the 7th Interna-
tional Conference on the Theory and Application of Diagrams (Diagrams 2012).
    Euler diagrams represent relationships between sets, including intersection,
containment, and disjointness. These diagrams have become the foundations of
various visual languages and have notably facilitated the modelling of, and log-
ical reasoning about, complex systems. Over the years, they have been used
extensively in areas such as biosciences, business, criminology and national se-
curity to intuitively visualize relationships and relative cardinalities of sets. This
widespread adoption has allowed analysis of complex collections of data.
    Euler Diagrams 2012 covered all aspects of Euler diagram research, partic-
ularly in areas such as logic and reasoning, drawability, generation and layouts,
readability and aesthetics, information visualization and data exploration, and
evaluation including comparison to other representations. After two successful
workshops in 2004 and 2005, this third Euler Diagrams workshop once again
brought together researchers with diverse backgrounds. Participants from both
academia and industry included: mathematicians; computer scientists; experts
in visualization, human-computer interaction and artificial intelligence; informa-
tion designers; and users from various application areas.
    Euler Diagrams 2012 solicited long and short papers, of which we accepted
eight long papers and one short paper. Every submission was reviewed by three
members of the Program Committee who are experts in the relevant topics. In
addition to the paper presentations, we were privileged to have Tim Dwyer from
Microsoft Corportion, USA to give a keynote talk on “Developing a Visual Code-
dependency Analysis Tool for the Visual Studio IDE: Research Meets Practice
in Showing Containment in an Interactive Diagramming Tool”.
    We owe thanks to many people for helping to make Euler Diagrams 2012 a
success. First and foremost, we are grateful to our Program Committee consisting
of twelve distinguished experts from both academia and industry. Their insight-
ful reviews provided invaluable feedback to authors of submitted papers. David
Dailey, John Howse, Nathaniel Miller and Nik Swoboda kindly agreed to act as
Session Chairs. As part of the Organizing Committee of Diagrams 2012, we are
indebted to the General Chair, Peter Rodgers, the Workshop Chair, Nathaniel
Miller, and the Publicity Chair, Aidan Delaney, for making the process of orga-
nizing the workshop as smooth as possible. We also thank Gem Stapleton for her
indispensable advice. Finally, we acknowledge the US National Science Founda-
tion for funding many of the PhD students to attend Diagrams 2012, and hence,
to also attend our workshop.
