yWorks employee here, though not working on yEd. As shezi noted, it's a demo for the capabilities of our commercial diagramming library. Said library handles displaying and editing graphs, automatic layout and analysis algorithms and yEd showcases all of those things to some extent. The library itself is quite customizable, though, so our customers often create applications for very specific diagrams and interactions with it. I would assume, however, that the intersection between yEd users and yFiles licensees is fairly small, though. It still remains a good showcase for what developers could do with the library (along with the 100+ demo applications that ship with it [1]).
