Diagramming link dump

I got a few diagramming links piling up.

• JS sequence diagrams, very nice look, parses a sequence diagram description language.
• Chart.js looks neat.
• A guy that blogs about UML, talking about different modes of use for it, which I find pretty enlightening.  In case you're wondering, I favor "UML as programming language".
• A UML sharing service (UMLbin).  Neat idea.  But the only download option is a PNG - no source.  So that's disappointing.
• And Visualizing Social Structures, a historical retrospective.
