Jason Kottke turned me on to this fantastic data visualization by Zach Beane, showing this year’s box office gross for American movies. Like this related graphic at The New York Times , it uses the x -axis for time and the height of each node to indicate revenue, but presents the data in a way that allows readers to infer four additional kinds of information — without having to complicate the graphic: The position on the y -axis represents each film’s rank, revealing the importance of a strong opening weekend (but begging the question of how The Bucket List, which opened in 23rd place, became the #1 movie in America the following week; something to do with New Year’s Day?)
