In infographics, the pencil is still the mightiest weapon

Even if I have mostly focused on data visualization in the past few years, I've kept an eye on the careers of many infographics designers, as I want to write a book about pictorial explanations at some point. Adolfo Arranz is one of those designers. His work is consistently impressive. He has just published a post comparing his sketches with the pieces that finally got published. Wow.
