6. LinkedIn: Clustering Your Professiona... > Geographically Clustering Your Netwo...

Geographically Clustering Your Network

With the know-how to access extended LinkedIn profile information, and a working knowledge of common clustering algorithms, all that’s left is to introduce a nice visualization that puts it all together. The next section applies k-means to the problem of clustering your professional contacts and plots them out in Google Earth. The section after it introduces an alternative visualization called a Dorling Cartogram , which is essentially a geographically clustered bubble chart that lets you easily visualize how many of your contacts live in each state. Ironically, it doesn’t explicitly use a clustering algorithm like k-means at all, but it still produces intuitive results that are mapped out in 2D space, and it conveys a semblance of geographic clustering and frequency information.
