docstr: Specifies the URL of the image to be used. The URL must be
  accessible from the domain where the plot code is run, and can
  be either relative or absolute.
  
  The 'source' property is an image URI that may be specified as:
    - A remote image URI string
      (e.g. 'http://www.somewhere.com/image.png')
    - A data URI image string
      (e.g. 'data:image/png;base64,iVBORw0KGgoAAAANSU')
    - A PIL.Image.Image object which will be immediately converted
      to a data URI image string
