docs: def _set_context(context=None, font_scale=1, rc=None):
      """
      Set the plotting context parameters.
  
      NOTE: This is an internal method from Seaborn that is simply used to
      create a default aesthetic in yellowbrick. If you'd like to use these
      styles then import Seaborn!
  
      This affects things like the size of the labels, lines, and other
      elements of the plot, but not the overall style. The base context
      is "notebook", and the other contexts are "paper", "talk", and "poster",
      which are version of the notebook parameters scaled by .8, 1.3, and 1.6,
      respectively.
  
      Parameters
      ----------
      context : dict, None, or one of {paper, notebook, talk, poster}
          A dictionary of parameters or the name of a preconfigured set.
      font_scale : float, optional
          Separate scaling factor to independently scale the size of the
          font elements.
      rc : dict, optional
          Parameter mappings to override the values in the preset seaborn
          context dictionaries. This only updates parameters that are
          considered part of the context definition.
