Create a math visualization infographic about "[math concept/topic]", with the goal of helping the reader intuitively understand: what it is, why it holds, what the geometric/structural intuition is, and how it behaves across different scenarios. The image should look like a high-quality math lecture handout + a hand-drawn educational poster: elegant, clear, rich in information, but not cluttered. Visual style: portrait or landscape, clean light paper background, dark-blue title, black/dark-gray body lines, with a few elegant blue, teal, gold, and red accent colors. Use rounded-corner cards, thin-line borders, numbered labels, hand-drawn arrows, local zoom-in boxes, and a summary bar. The overall look should be beautiful, balanced, and academic, making the "structure" and the "why" of the concept clear at a glance.
