Dashboards have become popular in recent years as uniquely powerful tools for communicating important information
at a glance. Although dashboards are potentially powerful, this potential is rarely realized. The greatest display
technology in the world won't solve this if you fail to use effective visual design. And if a dashboard fails to tell you
precisely what you need to know in an instant, you'll never use it, even if it's filled with cute gauges, meters, and traffic
lights. Don't let your investment in dashboard technology go to waste.
This book will teach you the visual design skills you need to create dashboards that communicate clearly, rapidly, and
compellingly. Information Dashboard Design will explain how to:
Avoid the thirteen mistakes common to dashboard design
Provide viewers with the information they need quickly and clearly
Apply what we now know about visual perception to the visual presentation of information
Minimize distractions, cliches, and unnecessary embellishments that create confusion
Organize business information to support meaning and usability
Create an aesthetically pleasing viewing experience
Maintain consistency of design to provide accurate interpretation
Optimize the power of dashboard technology by pairing it with visual effectiveness

Introduction
Few phenomena characterize our time more uniquely and powerfully than the rapid rise and influence of
information technologies. These technologies have unleashed a tsunami of data that rolls over and flattens
us in its wake. Taming this beast has become a primary goal of the information industry. One tool that has
emerged from this effort in recent years is the information dashboard. This single-screen display of the
most important information people need to do a job, presented in a way that allows them to monitor what's
going on in an instant, is a powerful new medium of communication. At least it can be, but only when
properly designed.
Most information dashboards that are used in business today fall far short of their potential. The root of the
problem is not technologyat least not primarilybut poor visual design. To serve their purpose and fulfill their
potential, dashboards must display a dense array of information in a small amount of space in a manner
that communicates clearly and immediately. This requires design that taps into and leverages the power of
visual perception to sense and process large chunks of information rapidly. This can be achieved only when
the visual design of dashboards is central to the development process and is informed by a solid
understanding of visual perceptionwhat works, what doesn't, and why.
No technology can do this for you. You must bring this expertise to the process. Take heartthe visual design
skills that you need to develop effective dashboards can be learned, and helping you learn them is the sole
purpose of this book.
If the information is important, it deserves to be communicated well.
Acknowledgments
Without a doubt I owe the greatest debt of gratitude to the many software vendors who have done so much
to make this book necessary by failing to address or even contemplate the visual design needs of
dashboards. Their kind disregard for visual design has given me focus, ignited my passion, and guaranteed
my livelihood for years to come.
Now, on to those who have contributed more directly and personally to this effort. As a man, I will never be
able to create, shelter, and nourish an emerging life within this body of mine. In recent years, however, I
have recognized and pursued the opportunity to breathe life into the products of my imagination and pass
them on to the world in the form of books. Writing a book is a bit like bearing a child. Working with a
publisher to help the child learn to walk before venturing into the world is a lesson in trust. The folks at
O'Reilly Media have taught me to entrust to thembeginning with unspeakable angst, but proceeding through
unfaltering steps toward ever-increasing comfortthe collegial care of this beloved child. Many at O'Reilly
have contributed so much, but two in particular have stood by my side from the beginning with soothing
voices of confidence and calm. My editor, Colleen Wheeler, knew when to listen in silence, when to tease me
out of myopia, and when to gently remind me that I was in her considerate and considerable care. My
acquisitions editor, Steve Weiss, sought me out and wooed me through months of thoughtful discussion into
the O'Reilly fold. He gave assurances and has made sure that they were fulfilled.
