 NetworkX (NX) is a Python package for the creation, manipulation, and 
 study of the structure, dynamics, and functions of complex networks.
 Features:
 * Includes standard graph-theoretic and statistical physics functions
 * Easy exchange of network algorithms between applications, disciplines, 
   and platforms
 * Includes many classic graphs and synthetic networks
 * Nodes and edges can be "anything" (e.g. time-series, text, images, 
   XML records)
 * Exploits existing code from high-quality legacy software in C, C++, 
   Fortran, etc.
 * Open source (encourages community input)
 * Unit-tested
 
 Additional benefits due to Python:
 * Allows fast prototyping of new algorithms
 * Easy to teach
 * Multi-platform
 * Allows easy access to almost any database
