Chapter 15.2, Problem 15.7CP

Program Plan Intro

Scene graph:

• A scene graph denotes a hierarchical data structure used for organizing components in JavaFX GUI.
• It denotes a tree-like structure that would contain nodes.
• The three types of nodes in scene graph are shown below:
  • Root Node:
    • A scene graph can have a single root node only.
    • It denotes a parent of other nodes in scene graph.
    • It denotes first node in structure.
  • Branch Node:
    • A branch node can have other nodes as children.
    • A scene graph might have more than one branch nodes.
  • Leaf Node:
    • A scene graph can have multiple leaf nodes.
    • A leaf node does not have any children.
• The root node as well as branch nodes could have children.
• The leaf node cannot have any children.
