List nodes control how data is structured, ordered, filtered, and distributed through the node graph. They are the backbone of parametric logic - determining which geometry receives which values, how collections are sorted, and how data trees branch and merge. The package has four groups: List (access, filter, sort), Sequence (generate number series), Set (combine and compare lists), and Tree (manage hierarchical data structures).

List
