Class HierarchyLayout

A new version of a hierarchy layout, which can better handle upstream links and multiple parents. This layout runs in 3 stages -

  1. placement of nodes into layers
  2. reordering nodes in layers to minimise edge crossing
  3. placement of nodes into final layout

      Node/Group to get absolute position for.

    • Optional parameters: LayoutParameters

      Constructor parameters. May contain a custom locationFunction.
