The generator offers six different structural layouts: Hierarchical (traditional top-down), Spider (radial from center), Flowchart (sequential), System (interconnected), Chain (linear progression), and Cross-linked (web-like). Each structure serves different purposes – Hierarchical works well for showing classifications, Spider for brainstorming, Flowchart for processes, System for complex relationships, Chain for sequential concepts, and Cross-linked for showing multiple connections between ideas.
