English: Samples from the cosine variant of the bivariate von Mises distribution. The green points are sampled from a distribution with high concentration and no correlation (${\displaystyle \kappa _{1}=\kappa _{2}=200,\kappa _{3}=0}$), the blue points are sampled from a distribution with high concentration and negative correlation and the red points are sampled from a distribution with high concentration (${\displaystyle \kappa _{1}=\kappa _{2}=200,\kappa _{3}=100}$) and no correlation (${\displaystyle \kappa _{1}=\kappa _{2}=20,\kappa _{3}=0}$).
