Here are two quick resources that can be used for an introduction to the concept of data visualizations as part of the investigate performance task. The first is a 1 Minute and 45 second video entitled "The Value of Visualization" which can be found on Vimeo at: http://vimeo.com/29684853#at=0 . The second resource is a company called Tableau that you can reach at Tableau.com. They have quite a few white papers on the topics of Big Data, Data Visualizations, and related topics. One publication I came across entitled "The Five Most Influential Data Visualzations of All Time" looks like something very interesting to share with students again as a introduction to data visualization and why it is important.
