It would be really nice if there was some standard way in HepRep to define an initial view. This is quite critical since currently nothing may be visible when WIRED View is opened, and user does not know whether to zoom in or out. As a workaround just calling "Fit In Window" when displaying initial view might work.

I guess ideally it would be possible to create several standard views, e.g. Vertex View, Full View, XY View etc which would then appear in the WIRED (or other tool's) View Menu.
