Abstract:

Data visualization is the graphical representation of information. Information technology combines the principles of visualization with powerful applications and large data sets to create sophisticated images and animations. Representing large amounts of disparate information in a visual form often allows you to see patterns that would otherwise be buried in vast, unconnected data sets. Data visualizations offer one way to harness infrastructure to find hidden trends and correlations that can lead to important discoveries. Visual literacy is an increasingly important skill, and data visualizations are another channel for students to develop their ability to process information visually.
