LOVE this space launches chart in @TheEconomist. Applaud their highlighting data driven stories in a new section. Still so crazy to me that all this great work goes uncredited (as do all the words in every issue). Thanks for the beautiful data viz anonymous graphic reporter! pic.twitter.com/uMkW8j0d3a
