Visual Topology provides a set of open source projects which together implement tools for building and running topologies - executable graphs of linked components.

• Graphical tools for building topologies
• Backend engines for executing topologies (currently implemented - Javascript and Python)
• Libraries for creating web applications backed by topologies
