A wide variety of structural information can be represented as a graph. The automatic generation of graph representations has important applications in areas such as database, network, and software interface design. You will find this toolkit useful if:

* you want to reorganize your program, which requires first understanding all the existing relationships between types, procedures and source files
* you want to find weaknesses in the Internet backbone at the system level, not just at the individual channel level
* You're debugging a protocol or microarchitecture that's reduced to a finite state machine and you want to find out where the machine goes to error state
* you want to get a visual representation of a database schema, a knowledge base, or a distributed computing system.
* you want to get an overview of a group of related documents
* you want to identify patterns and interest groups based on a database of phone calls or emails
