dotty - A Customizable Graph Editor

       The lefty parser does not accept anonymous graphs.

dotty is a graph editor for the X Window System.  It may be run as a standalone editor, or as a front end
       for applications that use graphs.  It can control multiple windows viewing different graphs.

       dotty  is  written on top of dot and lefty.  lefty is a general-purpose programmable editor for technical
       pictures.  It has an interpretive programming language similar to AWK and  C.   The  user  interface  and
       graph  editing  operations  of dotty are written as lefty functions.  Programmer-defined graph operations
       may be loaded as well.  Graph layouts are made by dot, which runs as a separate process that communicates
       with lefty through pipes.

       If the input graph contains xdot attributes, dotty will use that to display the graph. Otherwise, it runs
       dot to obtain layout information.
