This book constitutes the proceedings of the 23rd
International Symposium on Graph Drawing and Network Visualization, GD 2015,
held in Los Angeles, Ca, USA, in September 2015.






The 35 full papers presented together with 7 short papers
and 8 posters in this volume were carefully reviewed and selected from 77
submissions. Graph Drawing is concerned with the geometric representation of
graphs and constitutes the algorithmic core of Network Visualization. Graph
Drawing and Network Visualization are motivated by applications where it is
crucial to visually analyze and interact with relational datasets. Examples of
such application areas include social sciences, Internet and Web computing,
information systems, computational biology, networking, VLSI circuit design,
and software engineering.



This year the Steering Committee of GD decided to extend
the name of the conference from the "International Symposium on Graph
Drawing" to the "International Symposium on Graph Drawing and Network
Visualization" in order to better emphasize the dual focus of the
conference on combinatorial and algorithmic aspects as well as the design of
network visualization systems and interfaces.
