Layouting

Direction

XOR

  • with overlaps

Meta Collapsing

XOR - top to bottom, left to right

• Show n features
  • Breadt-First, Depth-First

Collapsing of Levels

XOR

• Max levels (top-aligned), open the first n levels 🍍
• Set of levels, e.g., {1, 4, 5} -> Levels 1, 4, 5 uncollapsed, rest collapsed
  • Requires vertical collapsing in between #14

Collapsing of Children

Basic rule: left-aligned, collapse right to left

• Max children, e.g., 3 -> Maximum number of children per feature is 3 🍍
• Max total children, e.g., 7 -> Show at most 7 features in a level
