Mathematical Visualization Infographic Prompt

Please create a mathematical visualization infographic about "mathematical concepts/knowledge points" to help readers intuitively understand: what it is, why it holds true, the geometric/structural intuition, and how it behaves in different scenarios. The image should look like a high-quality math lecture handout + hand-drawn educational poster—elegant, clear, and informative without being cluttered. Visual style: vertical or horizontal, clean light-colored paper background, dark blue headings, black/dark gray body lines, accented with a few elegant blue, turquoise, gold, and red colors. Use rounded-corner cards, thin borders, numbered labels, hand-drawn arrows, partial magnification boxes, and summary columns. The overall design should be aesthetic, balanced, and academic, allowing one to immediately grasp the "structure" and "reasoning" behind the concept.

请创作一张关于「数学概念/知识点」的数学可视化信息图，目标是帮助读者直观理解：它是什么、为什么成立、几何/结构直觉是什么、在不同场景下如何表现。画面要像高质量数学讲义 + 手绘教育海报，优雅、清晰、信息丰富，但不要杂乱。

视觉风格：竖版或横版均可，干净的浅色纸张背景，深蓝标题，黑色/深灰正文线条，搭配少量优雅的蓝色、青绿色、金色、红色强调色。使用圆角卡片、细线边框、编号标签、手绘箭头、局部放大框和总结栏。整体要美观、平衡、有学术感，让人一眼看懂这个概念的“结构”和“为什么”。
