Nodes will be colored by contextual meaning -- projects, people, etc.
An example: the first image shows a central page with 4 related pages.
One of the related pages (on the right) has two sub-pages. As the mouse moves over that node, the bottom label displays the location. When the user clicks on that sub-node, the map recenters itself on the new central node.
