    Featureful. Reliable and extendable.

    yEd has pretty much all features as Dia and a lot more! It has a bit steep learning curve and sometimes a bit strange UI, but once you learn it you can do almost any diagram in it. It can even reorganize it automatically, if it gets messy!

    Line links not attached to objects. Better for drawing than diagramming though it is still possible.

    Not a GUI diagramming tool. By this logic graphviz is an alternative to Dia.

    PlantUML has no way to make a diagram or chart without knowing command line and learning a whole new markup language.
