/* =========================================================================
   Correlation: Linearity, Outliers and Shared Variance — tool styling
   -------------------------------------------------------------------------
   Shared page furniture comes from components/tool-kit.css. What is specific
   here is the scatterplot with its fitted line and ringed observation, and
   the three small "eyeball test" plots in the challenge.

   The ringed point is marked by a ring - a shape, not a colour - and each
   guess plot carries a written alternative beneath it stating how many
   points it holds and how they run, so the challenge is answerable without
   seeing the picture.
