The approach is good, although I'd present a different split,
which is probably difficult to do via a machine.

The predicates

IsConvergencePoint 
IsConnected 
PointsTo 
ExpandsTo 
Associated 

are on in the 'lines and curves and areas' domain of operation
(which the graphic artist works in).

the reader of the document does a mental translation of those into
things like 'face' 'house' 'process box' etc which are in a slightly
different domain.

Machine translation from one to the other is (probably) not automatable
today.

The approach is nice though, adding the rdf to an existing diagram without
screwing around with it. I didn't believe it realistic to insist on authors
drawing up documents to guidelines, hence followed the same approach, adding
data to the drawing for later extraction for alternative presentation.
