I meant "few" not "view".
Anyway, here is another site:English Grammar Revolution: Grammar Made Easy
This one does more teaching than simply showing the diagrams.
Elizabeth O'Brien seems to me to be the kind of teacher that I would like to have. You may have to pay a little amount to download her "booklet", but it is worth it if you want to learn the art.
There are some mistakes in her work -- minor for the most part. My biggest objection is the use of the word "verb" where I think the word "simple predicate" is called for. There is some other crossing of terms from morphology and terms from syntax.
Simple predicates are always and only verbs, but verbs are not always and only simple predicates.
