The chart on the right is what RelativeFinder generates. On the left is a slight variation that seems more understandable.
The lefthand modified 2 cousin pedigree has a bit more white space down the centerline that makes it look more like 2 sets of 2 columns instead of 1 set of 4 columns. And I dropped the saturation of the parent outside of the blood relationship. (The chart is my supposed relationship to Pres. George Washington.)
