How do you show all levels of an organization in Microsoft visio 2007?

To show levels of organization using Visio i would suggest you to use layers in Visio. n general, all Visio diagrams have two built-in layers: the Connector, and another that represents the shapes (this layer can have different names based on what kind of diagram you have open). Layers for a diagram are viewed, edited, and used in the Layer Properties dialog box.
