Published specification : http://www.graphviz.org/doc/info/lang.html Applications which use this media : dot, neato, ... graph layout engines from the graphviz package. An emerging class of networked graph viewers and GUIs. Multiple third party applications: http://www.graphviz.org/Resources.php Additional information : 1. Magic number(s) : (not available) 2. File extension(s) : .gv .dot 3. Macintosh file type code : (not available) 4. Object Identifiers: (not available) Graphviz is a mature family of tools for processing graphs in the DOT language. The use of ".dot" as a file extension has become problematic as we see more GUI and networked graph tools since the same extension as used by MS Word. The graphviz tools are open-source and widely used. I'm sure we'd be willing to standardize this format if there was interest in us doing so. Person to contact for further information : 1.
