Please create a mathematical visualization infographic about "[math
concept / topic]." The goal is to help the viewer intuitively understand
what it is, why it works, its geometric or structural intuition, and how
it behaves in different contexts. The visual should feel like a high-
quality math lecture handout combined with a hand-drawn educational
poster. It should be elegant, clear, and information-rich, but not
cluttered. Visual style: either portrait or landscape is fine. Use a
clean, light paper-like background, with a deep blue title and black or
dark gray lines for the main content. Add a small number of refined
accent colors such as blue, teal, gold, and red. Incorporate rounded-
corner cards, thin borders, numbered labels, hand-drawn arrows, zoom-in
callout boxes, and a summary section. The overall design should be
aesthetically pleasing, balanced, and academic, allowing the viewer to
grasp the structure of the concept and why it works at a glance.
