Dewey Calendar | Pehr Hovey | http://pehrhovey.net

 

This visualization shows how library transactions are distributed over the the main Dewey Decimal categories (000 through 900).

Each column is one day of the week. The height of each column is proportional to the number of transactions on that day.
Lines connect each category per day so the weekly trend is visible. Federal holidays (library closings) are highlighted in blue to demonstrate
why certain days have unusually low transaction counts.

A column can be clicked to expand it and show the distribution of 100 Dewey sub categories: 100,110, 120, etc.
