So, rendering the graph as a bar set with proper numbering and perhaps a detailed legend would convey the information just as well and avoid confusion as to what points between "Movies" and "Books" mean (although that very question has a very elementary one-word answer followed by a look of ever-so-slight amusement).

Still far from worst graph of the decade. For an example of a worse and far more hilarious case, over the top of my head: http://www.mydailyroast.com/?p=311

Have a nice day.
