A New Political Pattern Emerges

The network visualization above shows patterns of top-selling political books after the 2006 mid-term elections, and during the 2006 holiday buying season.

The maps are based on book buying data: "Customers who bought this item also bought...". Two books are linked if they are often bought by the same customers. Specifically, we looked at the top 10 political books and their network neighborhood. Our InFlow software created the visualization based on the data alone.

On the map we see three, possibly four, clusters. The red and blue clusters remain, as does the purple cluster, which initially showed up in early 2006. During 2004 the readers of political books were divided in to two obvious camps -- red and blue. In previous analysis during 2006, the purple books reflected a "middle ground" between the right and left books. In this analysis the purple books no longer hold that position. They are only connected to the blue books. The purple books seem to be splitting into two smaller clusters -- one around books that address religion and the other around books about economics. The key bridging books between left and right readers are "The Looming Tower" and a novel, "The Innocent Man".
