MiniEdit is a Mininet application in Python that lets you develop Software-Defined Networks in a visual manner. You can create networks visually for a Mininet emulation using MiniEdit, or load an existing Mininet topology (saved as an .mn file) into MiniEdit to edit it. You may also emulate the networks directly through the MiniEdit's GUI, which invokes Mininet as its backend for the emulations.

In this recipe, we will load an existing .mn file to recreate a Python program and emulate the network represented by it.
