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.
The file name is optional. If present, the graph contained in that file is
displayed in the
dotty window.

The lefty parser does not accept anonymous graphs.
