Minimal GUI (Graphical User Interface) generated by the “pycxsimulator.py” module. A three-button minimal GUI window is displayed at the top, together with the large main window showing the simulation result that is dynamically updated in real time. The main window also comes with several matplotlib-default GUI buttons for zooming and saving images, etc. (bottom). Simulations of cellular automata, dynamical networks and agent-based models are to be operated using this simple GUI.
