This book constitutes the proceedings of the 16th International Conference on Algorithms and Computation, WALCOM 2022, which was held in Jember, Indonesia, during March 24-26, 2022.This proceedings volume contains 30 full papers which were carefully reviewed and selected from a total of 89 submissions and 3 invited papers.

Automatic Graph Drawing is concerned with the layout of relational structures as they occur in Computer Science (Data Base Design, Data Mining, Web Mining), Bioinformatics (Metabolic Networks), Businessinformatics (Organization Diagrams, Event Driven Process Chains), or the Social Sciences (Social Networks).In mathematical terms, such relational structures are modeled as graphs or more general objects such as hypergraphs, clustered graphs, or compound graphs. A variety of layout algorithms that are based on graph theoretical foundations have been developed in the last two decades and implemented in software systems.After an introduction to the subject area and a concise treatment of the technical foundations for the subsequent chapters, this book features 14 chapters on state-of-the-art graph drawing software systems, ranging from general "tool boxes'' to customized software for various applications. These chapters are written by leading experts, they follow a uniform scheme and can be read independently from each other.

With 133 registered participants from 27 countries, including 19 participants fromindustry,theInternationalSymposiumonGraphDrawing2001(GD2001) that took place in Vienna, September 23-26, 2001, clearly demonstrated that the graph drawing community is still growing.

In addition, we had the pleasure of enjoying invited presentations by Alexander Schrijver and Eduard Gr. oller that mark extreme points of the wide spectrum of graph drawing, the mathematical foundations and the computer graphics, respectively.Wehavecompiledthewrittenversionsofthesecontributionsinthe same order as they were presented during the conference.

GD 2001 hosted a software exhibition that gave participants and guests the opportunity for hands-on experience with state-of-the-art graph drawing tools.

The ?nal contribution in this volume is a report on a traditional component of all graph drawing conferences that is a serious and a fun event at the same time: the Graph Drawing Contest 2001 organized by Franz Brandenburg. We would like to thank all contributors for the pleasant cooperation.
