Over the last few days I was looking at some new cool way to present and analyze data using visual methods. I came across InfoRapid Knowledge Portal which is a unique applications that present vast amounts of data in an attractive manner and user friendly interface.Here's a quick example of visual presentation of a knowledge map of the term: "San Francisco" in Wikipedia database using inforapid.org:

So I highly recommend this site and the application for many uses such as representing information in a better and easier manner, decision taking, and creating many different types of diagrams.
Have a good one!
