<longdescription>
graphviz is a set of graph drawing tools for Unix or MS-Windows
(win32), including a web service interface (webdot). Source code and
binary executables for common platforms are available. Graph drawing
addresses the problem of visualizing structural information by
constructing geometric representations of abstract graphs and networks.
Automatic generation of graph drawings has important applications in key
technologies such as database design, software engineering, VLSI and
network design and visual interfaces in other domains. Situations where
these tools might be particularly useful include:
* you would like to restructure a program and first need to
understand the relationships between its types, procedures, and source
files.
* you need to find the bottlenecks in an Internet backbone - not
only individual links, but their relationships
* you're debugging a protocol or microarchitecture represented as a
finite state machine and need to figure out how a certain
error state arises
* you would like to browse a database schema, knowledge base, or
distributed program represented pictorially
* you would like to see an overview of a collection of linked
documents
* you would like to discover patterns and communities of interest in
a database of telephone calls or e-mail messages
