I would add to your list two tools: 

Interactive Development Environments (IDE) sells Software Through
Pictures which included a diagram editor called Picture Editor.  I've  used it
as have some of the people who work for me.  Reasonably good if you are
happy with their pallette of predefined symbols.  Pallette contains
most of the SA/SD type symbols you might expect. Binary distribution.
Reuse in another program subject to permission and possible royalties to
IDE.


Hewlett-Packard sells a "Motif Graph Widget", but only through special
request to their Corvallis Plant.  The Graph Widget evolved from original work
done by Luis Miguel (now PhD candidate at UC Berkeley) when he worked at
HP's Software Methods Lab in Cupertino, CA and was extensively rewritten for
Motif by Doug Young (author of Motif Programming book, now at Silicon
Graphics) when he was at HP Labs in Palo Alto.  Now classified as a "specials"
product, it is available only via Corvallis which develops HP's other Motif
implementations.

The Graph Widget is a full-fledged Motif manager widget which
displays nodes (any arbitrary Motif widget or gadget), and arcs
(undirected, directed, bi-directed, colored, labeled, variable width,
arrow/line widgets).  Can display unconnected forests of graphs, including
graphs with cycles.  Does a great job laying out hierarchical structures,
and a good job with many other graphical layouts. Supports edit modes
for repositioning nodes, subtrees, deleting and adding new nodes and
arcs.  Supports linking to arbitrary user specified callbacks.  Comes
with a set of useful test programs and examples that you can evolve your
own diagram editor from.  Sold only in SOURCE form.  No royalties due
on binary products resold by others that reuse the widget. IMHO, a nice,
very versatile tool for building applications.
