This book constitutes the proceedings of the 23rdInternational 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 papersand 8 posters in this volume were carefully
reviewed and selected from 77submissions. Graph Drawing is concerned with the geometric
representation ofgraphs and constitutes the algorithmic core of Network Visualization.
GraphDrawing and Network Visualization are motivated by applications where it iscrucial to
visually analyze and interact with relational datasets. Examples ofsuch 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 extendthe name of the conference from the International Symposium on GraphDrawing
to the International Symposium on Graph Drawing and NetworkVisualization in order to better
emphasize the dual focus of theconference on combinatorial and algorithmic aspects as well as
the design ofnetwork visualization systems and interfaces.
