context_page_description: The Craig plot, named after Paul N. Craig, is a plot of two substituent parameters used in rational drug design.
  Two most used forms of a Craig plot are
  plotting the sigma constants of the Hammett equation versus hydrophobicity
  plotting the steric terms of the Taft equation against hydrophobicity
