Example of the final result of the SCMS algorithm in 2D space. Black dots mark the points of the skeleton. Along with the skeleton, the colour-coded kernel density estimator is plotted. Tracers are marked with green points. The contour line is plotted with cyan colour at the threshold τ value. The blue circles represent the virial radius of the two massive clusters (M_vir > 10¹³ M_⊙ in the 2D space. This skeleton was extracted from a thin slice (~1.2 Mpc thick) in region D6 at redshift z = 0.
