The new computation engine will interpret natural language questions like:
What is the GDP of France ? It provides a historical graph of the GDP of France and definitions of GDP and has dropdowns for drilling deeper into the range of presented information.

Lexington ? Based on your location it will assume which Lexington is being referred to and provide information on it. There is a selection list to look at other possible Lexingtons.

It looks like a very useful new way to analyze and find information.

Any numberical information that is presented can easily be made in charts and graphs as the system is built with Mathematica functionality. The Mathematica capabilities enable very powerful uses of functions and high level math manipulations.
