The following message was posted to comp.graphics, but I think it has
high relevance to our newsgroup as well. Let me know what you think,
and don't forget to reply to the poster directly, too.

Subject: Object-oriented classification of visualization "idioms"
Date: 7 Feb 91 17:13:11 GMT
Organization: The Mitre Corp., Bedford, MA.
I am interested in developing an object-oriented class hierarchy of
useful "idioms" in scientific visualization, such as maps, spatial
fields, etc. (More precisely this would be a multiple-inheritance
heterarchy.) This would be the basis of an Lisp or Smalltalk-based
scientific visualization environment. I am particularly interested
in what the higher-level abstract classes or "mixins" should look
like.
I already know of the following related efforts:
Lisp-Stat
S-Plus now has some object-oriented features
CSIRO in Australia has done some classification
Wehrend (Univ. Colorado) has also
Does anyone know of any other research in this field that they could
supply me with pointers to? Also, if anyone has any ideas on this
subject they would like to share, I would greatly appreciate it.
Thanx very much in advance!

Also, if anyone has any ideas on this The work currently being done at Xerox PARC on the "Rooms" interface is spawning new metaphors of visualization, primarily for navigation of huge information spaces. If I named these entities, I'd call them "Spindles", "Coatracks", or whatever else they might look like; but the point is that they are decidedly novel objects, which would extend anybody's hierarchy. Also, considering the source,they are probably being developed in an object-oriented context anyway, simplifying a merge into Livinchouk's hierarchy. Similarly, if less dramatically, Doug Lenat's work at MCC on the CYC knowledge base is producing neat visualization modalities, to deal with similar problems. It's worth a look.
