Library Loans by Media Modernity by Darren Hardy

This visualization categorizes media into 4 classes based on the modernity of the media (e.g., Books are in the first class, and DVDs are in the last class). It draws a histogram of the checkout volume per category per day for the entire corpus from June 2005 to January 2009.

Written for MAT 259 (Legrady): Linear Data Flow Project, 22 January 2009.
