Undirected Graphical Models in Haskell

I developed a Graphical User Interface in Haskell for the underlying library.

It is a basic graph editor. We used this module internally for the development
of our project. Later on as this tool helped us a lot to ?gure out several bugs
inside our code- work, we thought that it is worth a mention.This tool is built
upon GTK+ and Graphviz. GTK+ (GIMP Toolkit) is a cross-platform widget toolkit
for creating graphical user interfaces. (ref: Wikipedia) It is also the
fundamental user interface toolkit of object model environment for most of the
*nix operating systems. Graphviz (short for Graph Visualization Software) is a
package of open-source tools initiated by AT&T Labs Research for drawing graphs
speci?ed in DOT language scripts. (ref: Wikipedia).

This editor could be a full-blown integrated development environment to work
with com- plex graphs, thus there is a large scope for its continued
development. A lot of visual elements could still be picked up from the DOT
