Open Office-Draw

• has connectors that work (follow moved node)

• export as SVG! (but not a native format, and can't import it!)

• doesn't appear to auto-word-wrap text within nodes, and SVG rendering is pretty bad

Many (but not all) use GML as a data format.

• good to have SVG view?

Mind Mapping is a subset.

Piddle is is a PyThon module for creating two-dimensional graphics in a manner that is both cross-platform and cross-media; that is, it can support screen graphics (e.g. [Quick Draw], Windows, Tk) as well as file output ([Post Script], PDF, GIF, etc.).

• looks like a Flash app, but does have export of JPEG/PNG/SVG

• hey, it actually does connecting vectors that move with either end! (Unfortunately they're right-angled, not pretty curves.)
