GraphWin File Format

The 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 GML format that is also supported by GraphWin).

Each 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:

  1. Global Parameters
  2. Node Attributes
  3. Edge Attributes
