seeking info on using snowflakes diagrams

[James Kroger]

I am posting this on behalf of Judea Pearl at UCLA. I apologize
in advance for not summarizing his efforts to date in seeking
this info; he didn't enumerate them in his request.

If you have any info you would like to share, I'll
be happy to relay it.
