code: def plot(points, ax=None, permutation=None, **kwargs):
      
      if not ax:
          fig, ax = pyplot.subplots()
      xs, ys = project_sequence(points, permutation=permutation)
      ax.plot(xs, ys, **kwargs)
      return ax
docs: Analogous to maplotlib.plot. Plots trajectory points where each point is a
      tuple (x,y,z) satisfying x + y + z = scale (not checked). The tuples are
      projected and plotted as a curve.
  
      Parameters
      ----------
      points: List of 3-tuples
          The list of tuples to be plotted as a connected curve.
      ax: Matplotlib AxesSubplot, None
          The subplot to draw on.
      kwargs:
          Any kwargs to pass through to matplotlib.
