The Eclipse Graphical Editing Framework (GEF) provides Eclipse-integrated end-user tools in terms of a Graphviz authoring (DOT editor, DOT Graph view) and a word cloud rendering environment (Tag Cloud view), as well as framework components (Common, Geometry, FX, MVC, Graph, Layout, Zest, DOT, and Cloudio) to create rich graphical Java client applications, Eclipse-integrated or standalone. All relevant information can either be found on github.com or on projects.eclipse.org.
GEF is participating in the annual Eclipse Simultaneous Release. We have finalized the Oxygen development stream and are now focussing on providing a first related bugfix/service release. See GEF@projects.eclipse.org for details.
