Visualizing Library Checkout Data in 2D Space

The second project for MAT259: Data Visualization involved exploring two dimensional space for visualizing data from the Seattle Public Library. I was interested in getting away from the traditional chart mentality and displaying data in a more unique way.

I settled on comparing two numerical quantities using a seesaw or balance/scale metaphor. I chose to enumerate the number of checkins and checkouts over time to analyze how they relate and how the balance changes over time.

Below is the rough concept sketch:
