5 Graph Description Language (GDL) - Absint

2 Overview
The Usage section contains the basics the user needs to know for using aiSee. Upon completing it
the user is able to do the following:
• Navigate through graphs
• Scale them
• Access additional information represented by each node
• Print graphs
The Advanced Usage section describes subgraphs, regions of nodes and different views of the
graph. Subgraphs and regions are used to structure graphs, thereby facilitating interactive exploration
of a graph. Finally, it is explained how layout and view parameters can be changed.
The GDL section is written for programmers who want to produce graph specifications from their
application program which can then be visualized using aiSee.
The Overview of the Layout Phases section provides an introduction to the internals of aiSee and
the underlying graph layout algorithms.
