Visualization has the power to reveal things that are hidden and generate new insights.
Theyrule is a perfect example. It allows you to visually map the kieretsu-like relationships between board members of major publicly-traded companies.

The data was collected from company websites and SEC filings in early 2004, so it may not be completely accurate - companies merge and disappear and directors shift boards.
See what you can discover.
