class_docstr: An immutable object representation of a visualization.
  
  Notes
  -----
  - A plot object is returned via the SFrame's or SArray's .plot() method
  
  Examples
  --------
  Suppose 'plt' is an Plot Object
  
  We can view it using:
  
  >>> plt.show()
  
  We can save it using:
  
  >>> plt.save('vega_spec.json')
  
  We can also save the vega representation of the plot without data:
  
  >>> plt.save('vega_spec.json', False)
