Activity on the Dia mailing list is hotting up around different diagraming tools and utilities.
As well as discussion on autodia and graphviz, dia coversion between dot / graphviz and other formats has been discussed, as well as James Micheal DuPonts introspector and directed graph tools.
Hopefully we can get a site and mailing list together so that graphviz, doxygen, dia, xfig and other developers and interested parties can keep up to date on techniques, tools and technologies as well as sharing code and ideas.
It will be nice to have dia convert easily to argouml or graphviz and others.
