- Well, thats more or less what I meant when I said this would make an
- ideal history mechanism.

- I'd prefer continuous zoom. I've seen widgets that do this, although
- I'm not sure where to find one. At any rate the problem is solvable.

-
- Not necessarily. As the first pass, it can be implemented as history
- for the browsers. Combine that with a saveable history, and you could
- just stick in the whole web into your history.
-
- On the other hand, I have (very distant) plans to lay a WWW browser on
- top of GhostScript. The browser would convert to postscript (also
- very convenient for printing). Ghostscript provides hooks for inserting
- mouse functionality, for the clicking, and away we go.
-
- The point is this: once that's done, hypertext postscript just sort of
- happens. It's there, with no additional work whatsoever.
-
- >Anyway, would hyper-graphical representations of the Web be useful?
- >If it is worthwhile, is it doable?
-
- Useful, yes; doable, yes; easy, no.
-
- The hard part is telling a computer to lay out the graph. You can assume
- a tree structure for any given local site, and be mostly correct, but I
- get the impression that the web is much more web-like across multiple
- sites. Evan assuming a tree structure, you have to make sure that non
- of your non-tree links are drawn on top of each other (in parallel, that is).
-
- Suppose we have a tree like this:
-
- A
- /|\
- / | \
- B C D
-
- If B, C, and D are all inter-linked, you can't draw their links and
- have them all be visible, unless you move one of B, C, or D; or use
- curved lines as links (anybody know how they generate the Usenet
- maps?). The specific solution is obvious, but generalizing it is not
- (to me, anyway).
-
- One concept that would probably help is grouping. It's common that a
- large body of documetation has a single entry point (or at least a
- small number of them). These could be displayed as a single element in
- the map, until a certain zoom level is reached. A good first guess
- would be that each site is a single entity.
-
- Parting Shot - does it occur to anyone that a Virtual Reality interface
- might provide the best view of the web, and the best way of traversing it?
- And does it also occur to anyone that this view of the web might look
- a lot like the cyberspace described by author William Gibson?
