New tools are making it easier to see and analyze complex dataCheaper technology and digital data are leading to innovationsData ranges from statistics to Facebook and Twitter postsSophisticated visualizations are also appearing on mobile phones (CNN) -- What's the first thing that goes through your mind when someone says the word "data"? For many of us, the first image is line graphs, pie charts and spreadsheets with columns and rows full of numbers that leave you bleary-eyed and a bit dazed. But what if someone were to say data can also mean what you post on Facebook and Twitter, the ratings you gave a restaurant, the photos you uploaded to Flickr or even, perhaps, what you feel. A bit of a reach? Not anymore. An emerging set of tools is making it easier than ever to track and compile all sorts of "data" and display it in a way that's relatively easy to understand.

You can now point your mobile phone at a street and instantly get ratings for restaurants. The U.S. Protovis. Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky.
