图形

🔷 图 (diagram) + 形 (form/shape) = a graphic figure or shape
图 means diagram or drawing; 形 means form or shape. Together 图形 is a geometric figure or graphic. Sound hook: túxíng has the same too- start as the English word two, and geometry starts with two points.
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.
形 — open frame 开 + hair/pattern 彡
形 combines 开 (originally a phonetic element suggesting the sound) with 彡, a radical depicting fine lines, hair, or decorative strokes. The 彡 part conveys the idea of visible markings or surface appearance, giving 形 its core meaning of 'shape' or 'form.' Over time it broadened to cover physical figure, appearance, and abstract form.
