Temporal: It’s all about time!
 Time is relative
 Data visualization techniques and
tools can help the reader grasp
more fully the context and
meaning of the data presented.

Temporal Visualizations
 Can help highlight information in a
way text alone cannot.
 As a concept has been around for
centuries. We’ve all seen timelines
in our textbooks haven’t we?
 Are often capable of eliciting an
emotional reaction, a la Al Gore
and his scissor lift.

A good overview of the topic:
 It’s About Time Visualizing
temporal data to reveal patterns
and stories by Hunter Whitney

Tool and Examples
 Google Trends

http://www.google.com/trends

You do have to login to Google. But this is free.

Allows you to look at what folks are searching over time. Lots of
prepared categories and you can explore more.

Cool video.

 TimeSearch
 http://www.cs.umd.edu/hcil/timesearcher/

“Widespread interest in discovering features and trends in timeseries has generated a need for tools that support interactive
exploration. We have built a prototype environment for interactive
querying and exploration of time-series data. Queries are built
using timeboxes: a powerful graphical, direct-manipulation
metaphor for the specification of queries over time-series datasets.
These timeboxes support interactive formulation and modification
of queries, thus speeding the process of exploring time-series data
sets and guiding data mining. The prototype includes windows for
timebox queries, individual time-series, and details-on-demand.
Other features include drag-and-drop support for� query-byexample and graphical envelopes for displaying the extent of the
entire data set and result set from a given query.”

 Free JavaScript library for manipulating
documents based on data.

Tools and Examples
 TimeFlow
 https://github.com/FlowingMedia/TimeFlow/wiki
 Allows you to analyze temporal data with five
different display modes: Timeline, Calendar, Bar
Chart, Table, and List.
 “Alpha” software. Buggy but they are working on it.

 “With this widget, you can make
beautiful interactive timelines….”

Tools and Examples
 Timeplot
 http://www.simile-widgets.org/timeplot/
 “Timeplot is a DHTML-based AJAXy
widget for plotting time series and
overlay time-based events over them
(with the same data formats
that Timeline supports).”
