Temporal Its 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.
  Weve all seen timelines in our textbooks havent
  we?
• Are often capable of eliciting an emotional
  reaction, a la Al Gore and his scissor lift.

A good overview of the topic

• Its 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.

Tools and Examples

• TimeSearch
• http//www.cs.umd.edu/hcil/timesearcher/
• Widespread interest in discovering features and
  trends in time- series 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-by-example and graphical envelopes for
  displaying the extent of the entire data set and
  result set from a given query.

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.

• 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).
