  The presence of physical systems whose characteristics change in a seemingly
erratic manner gives rise to the study of chaotic systems. The characteristics
of these systems are due to their hypersensitivity to changes in initial
conditions. In order to understand chaotic systems, some sort of simulation and
visualization is pertinent. Consequently, in this work, we have simulated and
graphically visualized chaos in a driven nonlinear pendulum as a means of
introducing chaotic systems. The visualized results obtained which highlight
the hypersensitivity of the pendulum to initial conditions can be used to
effectively introduce the physics of chaotic system. The simulation and
visualization programme is written in Python codes.
