Blobs (hackage): Blobs is a diagram editor for directed graphs. It is written in Haskell, using the platform-independent GUI toolkit wxHaskell. It is a community project at a fairly early stage of development - you are encouraged to get involved and improve it!  Blobs is a front-end for drawing and editing graph diagrams. You must add your own back-end engine if you want it to do some analysis or processing of the graph.
