Piero Zagami has built an interesting collection of visualizations around the United Nations Security Council Resolutions.

UNSC/R: this is the abbreviation for the United Nations Security Council Resolutions. These documents represent the decisions of the UN’s executive body. This massive amount of data (more than 1700 documents) doesn’t come in any organized form. The purpose of this project is to apply information design strategies to create visual maps of the Resolutions to help students in politics approach the subject of the UN.

Most of the visualizations appear circular in form, mapping colors to the quantity of resolutions passed over time.  It’s a massive tome of information, although I see no way to procure it.
