People (like myself) who occasionally play 1.Nc3 regard this as a main line and are not unhappy to see it. The book by Keilhack mentioned by @mleonard is excellent (as a general chess book) and points out all the transpositional possibilities that White might try to confuse you with. As a counter to some of the remarks made above, White does not always ...
I believe that we can "visualize" the space, as the area of the board that is available to each player to safely maneuver their pieces because it is the area they control.
