"prompt": "A precise and clear illustration of a geometric concept, showcasing a polygon that is circumscribed around a circle. The polygon should be a regular hexagon, with each of its sides tangent to the circle. The circle and the hexagon should be drawn with thin, solid lines, and the circle should be lightly shaded to distinguish it from the polygon. The background should be plain white to keep the focus on the geometric shapes. The style should be clean and professional, suitable for an educational textbook or dictionary. Ensure no text is included in the image to avoid any potential errors.",
"explanation": "這幅插圖展示了一個圓周圍的正六邊形，每一邊都與圓相切，這是「外切多邊形」的典型例子。正六邊形和圓都用細實線繪製，圓內部輕微著色以區別於多邊形。純白背景使圖形更加突出，整體風格專業且適合教育用途，有助於讀者理解這一幾何概念。",
"alt": "一個正六邊形外切於一個圓的插圖",
