Dewey Bubble!

Check out this cool data visualization of book borrowings! Click here to see an enlarged version of circulation statistics displayed as Dewey Blobs 🙂

The transactions are placed on a 32×32 grid based on their Dewey classification (000-999). Each transaction is shown as a semi-transparent circle with two attributes:

1) colour — based on the School the student making the transaction studies in
2) size — based on the popularity of the book (the larger the circle, the more times it’s been borrowed before)

From Dewey Blobs at Dave Pattern’s “self-plagiarism is style”.
