LinkedIn, the Facebook of Work contacts, has created a great new interactive visualization tool for your network, automatically grouping your contacts into areas by similar contacts and allowing you to browse the connections between them.  From Mashable’s description:

InMaps is an insight into who the major connections, bridges and influencers are in your network. People with bigger dots and their names in larger fonts have more connections (and typically more sway) in specific clusters. Perhaps that’s why my friend Neal Sales-Griffin, the former president of Northwestern’s student body, is so prominent in my professional graph.

The image above is my network, which you can view yourself at this shared link. The layout and grouping is done automatically, although you then enter your own titles for the groups.
