Visualizer is always a fragile part of NS-3.  If it doesn't show up, then something wrong with NS-3, installed python modules, or something else.  It is known to work on Ubuntu 12.04 with the instruction on the website, but I cannot say why it is not working.  May be something with installation of the template scenario... I'm not sure.

Visualizer is nice, but it is not the primary function of NS-3.  You still can simulate everything :)
