Visualize Your Network With InMaps
InMaps is an interactive, visual representation of your professional network that helps you better "understand the relationships between you and your entire set of LinkedIn connections," according to LinkedIn.
To try InMaps, visit its homepage and log in with LinkedIn. The map it generates is color-coded to represent different affiliations or groups from your career, such as previous employers, college classmates or industries you've worked in. As you zoom in, bigger names represent people who are the most connected with that specific cluster.
