<p>Read graphs in GML format.</p>
<p>“GML, the G>raph Modelling Language, is our proposal for a portable
file format for graphs. GML’s key features are portability, simple
syntax, extensibility and flexibility. A GML file consists of a
hierarchical key-value lists. Graphs can be annotated with arbitrary
data structures. The idea for a common file format was born at the
GD‘95; this proposal is the outcome of many discussions. GML is the
standard file format in the Graphlet graph editor system. It has been
overtaken and adapted by several other systems for drawing graphs.”</p>
