For the most part, it is what I expected: the major nodes in my professional network are driven by my current & past employers (PARTNERS+simons, Hill Holliday, One to One Interactive, THINK New Ideas), professional organizations (BIMA, MITX), and education (Bowdoin College).
The only real surprise is the inclusion of Compete, a local data analytics company, as a major node. While I have never worked for the company, I started out as a client of theirs about 5 years ago, and have grown into a "friend of the organization," both professionally and personally. So it makes sense that they're there, too (and I'm happy to be affiliated with such a smart group of folks).
Data visualizations like this are so interesting & informative. In one glance, you can quickly get a handle on my professional experience and the company I keep. Wouldn't it be cool if we could build similar visuals for a company or brand? LinkedIn Labs, are you working on this?
There are tools to visualize your Facebook network as well, but for the most part their value is unclear to me (basically, they all display some variation of which friends know each other).
