Water Margin 108 Heroes Relationship Map

Generate a poster titled "{argument name="topic" default="Relationship Map of the 108 Heroes of the Water Margin"}", using a style that combines classical Chinese ink-wash painting with modern infographic design. Center the composition on "{argument name="central figure" default="Song Jiang"}" as the main central node, placed in the middle of the image, with the 108 heroes of Liangshan radiating outward around it in tiers: the inner ring highlights the core 36 Heavenly Spirits, the outer ring shows the 72 Earthly Fiends, and the outermost ring adds the imperial court and antagonist factions, expressing the opposition between Liangshan and the imperial court. Present them using small portrait icons and nameplates, forming a complete array of all 108 heroes, and label the relationships between them. The overall structure should be complex yet clear, with a prominent center and distinct layers, conveying the complete relationship map of "the 36 Heavenly Spirits + the 72 Earthly Fiends + the imperial court forces."
