Computer Visualization: Added Value

I have recently discovered the Google Public Data Explorer which helps you to make large data sets to explore, visualize and communicate. While most charts and graphs displaying quantitative data can easily be printed without loosing fidelity and in fact are often enhanced by the higher resolution available by modern printers sometimes displaying data on a computer can add value. The charts and maps animated over time are examples of such added value since “the changes in the world become easier to understand.” [Google]
For instance, the first chart ​”correlates life expectancy and number of children per woman for most economies of the world. The bubble sizes show population, and the colors represent different regions of the world. You can also click on the play button to see data change over time.” [Google] Check it out!
