OBJECTIVES OF STATISTICS AND VISUALIZATION

Page 2: Introduction to data visualization 1

• It's a revolution. We're really just getting under way. But the march of quantification, made possible by enormous new sources of data, will sweep through academia, business and government. There is no area that is going to be untouched. Gary King

All of us now are being blasted by information design. It's being poured into our eyes through the Web, and we're all visualizers now; we're all demanding a visual aspect to our information...And if you're navigating a dense information jungle, coming across a beautiful graphic or a lovely data visualization, it's a relief, it's like coming across a clearing in the jungle.David McCandless

There is more data available to us now than we can possibly process. Every minute, Internet users add the following to the big data pool (i):

204,166,667 email messages sentMore than 2,000,000 Google searches684,478 pieces of content added on Facebook$272,070 spent by consumers via online shoppingMore than 100,000 tweets on Twitter47,000 app downloads from Apple34,722 "likes" on Facebook for different brands and organizations27,778 new posts on Tumblr blogs3,600 new photos on Instagram3,125 new photos on Flickr2,083 check-ins on Foursquare571 new websites created347 new blog posts published on Wordpress217 new mobile web users48 hours of new video on YouTube

How the Recession Reshaped the Economy, in 255 Charts

'How the Recession Reshaped the Economy, in 255 Charts' is sharing the 'pièce de résistance de 2014' prize so far and probably stands up well against anything else produced in recent memory. It is a modern masterpiece, supremely conceived and executed interactive graphic produced by Jeremy Ashkanas and Alicia Parlapiano for TheUpshot (more later), showing how job numbers have fared across 255 different industries in the past 10 years. Pigeonholing it is hard: it is a small-multiple-scatterplotted area charts extravaganza. Some of the tool-tip interactivity detail is extraordinary, which kind of makes the single complaint - that of the colour scale failing on the red-green issue - a slightly surprising oversight, albeit the position and direction of the charts provides the main encoding.
