GraphWin File Format
gw-format is the external graph format of GraphWin.
It extends LEDA's
graph format by additional parameters and attributes for describing
graph drawings. Note that the
gw-format was not defined to
be a readable or easy to extend file format (in contrast to the
format that is also supported by GraphWin).
gw file starts with a LEDA graph followed by a (possibly
empty) layout section. An empty layout section indicates that no drawing
of the graph is known, e.g. in the input file of a layout algorithm. If
a layout section is given, it consists of three parts:
- Global Parameters
- Node Attributes
- Edge Attributes
