How tiny can a data visualization be and still be meaningful? Edward Tufte pushed the limit of infographic density with his "sparklines," and now Dan Zarrella of Hubspot does something similar—with a micro-sized heatmap of a similarly micro-sized form of communication: the 140-character tweet. According to his visual analysis, links inserted into tweets are more likely to be clicked if they appear somewhere between the start and the middle of the tweet, not the end (as most of us would assume and do in practice).
Geeks love infographics. You know it, we know it. But it's easy to forget that data-viz isn't just catnip for the Twitterati — discerning gentlemen and -women 150 years ago loved it, too. BibliOdyssey knows this, and has curated a stunning set of Victorian-era infographics that would make Edward Tufte green with envy. (Indeed, he includes several of them in his landmark book Envisioning Information.)
Infographic nerds: Put away your iPad and prepare to slobber all over your desk. Edward Tufte is auctioning off rare books from his private library.
Tufte, for people who don’t worship at the altar of the Y-axis, is the high priest of modern information design — the man behind texts like Envisioning Information and Beautiful Evidence and a resolute PowerPoint hater. His library is a polymath’s trove (and, more to the point, a peek inside his incredible mind). It has first-edition Galileos, esoteric Russian space charts, and stunning Picasso etchings.
