Adapt Untangle into a graph editor.

Browse Source 
This builds a secondary GUI program sharing most of the Untangle code,
similar to galaxieseditor. You can still drag points around as in the
actual Untangle game, but also you can right-drag to add or remove an
edge between two points. And the 'copy to clipboard' action generates
the Untangle game id corresponding to whatever you ended up with.

This could be used for hand-designing actual Untangle games, but my
more immediate use for it is as a convenient method of constructing
test cases for the new graph testing code.
