Up to a hundred changes can happen to the data structure every few seconds and there are so many ways to view it, this would mean literally hundreds of thousands of pages that would have to be cached every few seconds just in case some operator decided to have a look at it from just that perspective. (And that's just with the current data set, which is expected to expand tenfold over the next few years)
Presentation logic is built into each object node because only "it" knows how to present itself based on information about the connected nodes and its own capabilities. For instance, if there is a problem somewhere in the network that affects "it" in one of many ways, "it" will show a warning color. This warning state propagates to other nearby nodes like site/area status pages, dynamic maps and so on. Except when an operator has told "it" not to, e.g. because a device is in maintenance mode.
I try not to think of this in terms of web pages but rather as a visual representation/manipulation of a dynamic data structure using SVG glued together with HTML.
It works beautifully. If only I could find a way to do it in paralell, it would be awesome.
