Create a horizontal 16:9 key character relationship diagram for [Work Title]. Design it as a clean, readable infographic map with the main character or central group in the middle, supporting characters arranged by faction, family, team, mentor, ally, rival, enemy, and other major relationship types. Use portrait-style character cards, short name labels, concise role descriptions, colored relationship arrows, group panels, and clear hierarchy. Keep the layout balanced, information-rich, and easy to scan, with enough spacing so names, arrows, and captions remain legible. Use a polished editorial infographic style suitable for explaining a story or fictional universe. Do not copy official franchise logos, exact copyrighted character portraits, trademarked UI, or protected artwork unless the user owns the rights; use original neutral visual interpretations when needed. Output aspect ratio: 16:9.
