In this chapter we elaborate on visualization techniques for time-oriented
data. We organized and structured this chapter according to our book .
Therefore, we ﬁrst motivate the importance of handling the temporal dimen-
sion explicitly by an example. Second, we deﬁne the needed concepts and
aspects of time and time-oriented data. The basic data foundations are cov-
ered already in Chapter 2. Here, we focus particularly on the characteristics
of time. Third, we give an overview of diﬀerent temporal data visualiza-
tion techniques. Fourth, we brieﬂy explain TimeBench, a data model and
software library for visualization and visual analytics of time-oriented data.
We conclude with an assessment of our categorization according to the vi-
sualization techniques presented, introduce the TimeViz Browser, which is
an interactive repository to support researchers and practitioners in ﬁnding
appropriate visualization techniques, followed by related readings, exercises,
