For users, recommendations can sometimes seem odd or counterintuitive. Visualizing recommendations can remove
some of this mystery, showing how a recommendation is
grouped with other choices. A drawing can also lead a user's
eye to other options. Traditional 2D-embeddings of points
can be used to create a basic layout, but these methods,
by themselves, do not illustrate clusters and neighborhoods
very well. In this paper, we propose the use of geographic
maps to enhance the denition of clusters and neighbohoods, and consider the effectiveness of this approach in visualizing similarities and recommendations arising from TV
shows and music selections. All the maps referenced in this
paper can be found in www.research.att.com/~volinsky/
