Brain Pickings put together a roster of thirty-seven writers for whom wake-up times were available. It became the base data set around which the set out to quantify, then visualize, the literary productivity of each author.
The end result — a labor of love months in the making — is this magnificent visualization of the correlation between writers’ wake-up times, displayed in clock-like fashion around each portrait, and their literary productivity, depicted as different-colored “auras” for each of the major awards and stack-bars for number of works published, color-coded for genre. The writers are ordered according to a “timeline” of earliest to latest wake-up times, beginning with Balzac’s insomniac 1 A.M. and ending with Bukowski’s bohemian noon.
