design
🗺️ 图案 = 图 (drawing/chart) + 案 (design/plan) → a designed pattern
图 means drawing, map, or chart; 案 means case, plan, or design. Together they form 图案, the planned drawing — a decorative pattern or motif used on fabric, tile, or illustration.
图 — enclosure 囗 + 冬 (simplified from 啚)
Originally written 圖, showing an enclosure 囗 around 啚, a depiction of a granary or rural settlement on a map. The whole character meant a map or chart of demarcated territory. Meaning later broadened to picture, diagram, or to plan/scheme.
