SysGraph: a system network grapher

SysGraph is a computational tool that can automatically generate system networks given the systemic features in a designed format. It is a component of SysAm: a resources development environment.

SysGraph, originally developed in SuperCard for Macintosh computers, is now re-developed in Java for different platforms. Here we include an applet to demonstrate what the user can do with SysGraph.

SysGraph applet demo: in order for the applet to work, you should have Internet Explorer 4.01 or higher installed on your computer. Other browsers may not work.

The applet provides two data samples: data.db1 and data.db2, which could be changed.

• For data.db1, the following conventions should be observed so that the data can be parsed correctly, a sample line for the data is: (at a single line, i.e., without a carriage return) entry condition: <SYSTEM NAME 1> term1 [realization statement] (probability)/ term2 & <SYSTEM NAME 2> term3/term4/term5, where entry condition and terms are necessary while others are optional. Please note that several characters are reserved and should not be included in the names, or more specifically () are reserved for probabilities; [] for realization statements, : for delimiter of entry condition and systems; & for systems and / for terms. If you have to use these symbols, put a slash before them.

• For data.db2, you can use "//" or "/* ...*/" to comment out part of the data.
