Foreword

It is with enthusiasm and excitement that I join the community of information

visualization researchers and designers in celebrating our still fresh accomplish-

ments of the past decade. However, even as we take pride in how far we have come,

we should acknowledge that these are just the ﬁrst steps of a much longer journey.

This book and the rich literature from conferences, journals, and a few pioneer-

ing books reveals a ﬂourishing, but still emerging academic ﬁeld, that ﬁghts for

recognition every day. Similarly, the product announcements from new and

mature companies, demonstrate the passionate commitment of venturesome

entrepreneurs who struggle to cross the chasm to commercial success.

Readers of the academic literature and corporate press releases probably believe

that the allure of information visualization is in ﬁnding appropriate representa-

tions of relationships, patterns, trends, clusters, and outliers. This belief is reinforced

by browsing through conference titles that weave together technical topics such as

trees, networks, time series, and parallel coordinates, with exotic verbs such as

zoom, pan, ﬁlter, and brush. However, I believe that the essence of information visu-

alization is more ambitious and more compelling; it is to accelerate human thinking

with tools that amplify human intelligence.

Chaomei Chen captures the spirit of this emerging academic discipline in this

second edition and cleverly uses knowledge domain visualization to trace the

growth and spread of topics. His survey highlights the dramatic progress during

the past ﬁve years in a way that celebrates and challenges researchers and develop-

ers. His numerous screenshots of research and commercial systems give a glimpse

of what is possible, but readers will have to see the demos for themselves and view

working products to get the full impact of the interaction dynamics.

Chen’s book shows us how the rapidly maturing information visualization tools

are becoming as potent as the telescope and microscope. A telescope enabled

Galileo to see the moons of Jupiter, and a microscope made it possible for Pasteur

to see bacteria that enabled him to understand disease processes. Similarly,

remarkable technologies such as radar, sonar, and medical scanners extend human

vision in powerful ways that facilitate understanding. The insights gained provide

support for air trafﬁc controllers, naval ofﬁcers, physicians, and others in making

timely and effective decisions.

The payoffs to users of information visualization tools will be in the signiﬁcant

insights that enable them to solve vital problems at the frontiers of their ﬁelds. By

extending their vision to higher dimensional spaces, users of information visual-

ization tools are making meaningful and sometimes surprising breakthroughs.

These users, such as genomic researchers, ﬁnancial analysts, or patent lawyers, are

often struggling to understand the important relationships, clusters, or outliers

hidden in their data sets. Their quest may last days or years as they seek to identify
