The VCG tool has been developed and tested on a Sparc ELC with
SunOs 4.1.3, X11 Release 5 and Release 6, and different ANSI C
and K&R C compilers.
It has been migrated to MS Windows 3.1. with the Visual C++
compiler and the library wxWindows.
It has further been tested on Solaris
(SunOs 5.3, gcc only), on a Silicon Graphics (IRIX 5.2),
on a IBM R6000 (AIX 2 with AIX Windows), on a HP-UX (X11R5, c89),
on a DecStation (ULTRIX, X11R5, gcc only), on Linux (X11R5, gcc),
and on OSF (X11R5, gcc). Recently, a user migrated the tool to
Based on the VCG code, the company AbsInt has developed a visualization
tool AISee. See
for more information.
I'm not involved in the AISee development anymore.
As far as I know, it is free for research usage.
Since I didn't have the time for porting myself lately, this is the
best choice for Windows 2000/95/NT.

The graph 5 with 75 specified nodes and 3983 edges consists of
21694 internal nodes and 23540 internal edge segments.
The tests were done using a xvcg (X11 version, compiled by
gcc version 2.6.3, gcc options -O -finline-functions).
They were done on a Sparc 10/30 (arch = sun4m) with 32 MB
The times include time for loading, layouting and displaying.
These examples are in color.
