While not really a map this simple tool does map affinity based on user’s literary tastes. It allows you to plug in any author you like and then it  shows other writers whom readers of your literary choice also selected. Supposedly, the closer the names, the more readers of X tend to like readers of Y. The dataset is taken from Gnod.  And if you can’t really on Gnod, what can you rely on ? Give it a spin. I had some fun with it, but found many proximity connections dubious at best.
