Alien vs. Predator

This is a quick visualization of data from the netflix prize. A vertical bar is drawn for every customer rating a movie. Ratings go from 1 to 5 stars (represented top to bottom.) Note how “Alien” (on the left) received many ratings of 4 and 5 stars, but “Predator” (on the right) mostly received ratings of 4 stars. This depicts approximately 50,000 customer ratings.

    Neat… is it still legible if you use the same colour for both sides? The left side is a little bit brighter I think, could be hiding something?

    Downloading the data now… it’s not exactly instant gratification territory, huh?

    Hmmmm. It also may simply be due to the fact that there are fewer ratings for Predator than Alien (~10% less I believe). Oh, also, heh, I noticed a bug in my code which used only about 75% of the ratings for Predator. Need to fix that. . . zoinks.

    Downloading the data is fun, even more fun is inserting it into a database, which took about 6 hours to run on my lowly machine.
