docs: def _axes_style(style=None, rc=None):
      """
      Return a parameter dict for the aesthetic style of the plots.
  
      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 color of the axes, whether a grid is
      enabled by default, and other aesthetic elements.
  
      This function returns an object that can be used in a ``with`` statement
      to temporarily change the style parameters.
  
      Parameters
      ----------
      style : dict, reset, or None
          A dictionary of parameters or the name of a preconfigured set.
  
      rc : dict, optional
          Parameter mappings to override the values in the preset seaborn
          style dictionaries. This only updates parameters that are
          considered part of the style definition.
