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 along 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 (http://uxmag.com/articles/itsabout-time)
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.
Tools and Examples 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.
Tools and Examples: TimeSearch
Tools and Examples D3.js http://d3js.org/ Free JavaScript library for manipulating documents based on data.
Tools and Examples
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.
Tools and Examples Timeline http://www.simile-widgets.org/timeline/ 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).
