Complex Mathematical Diagram with Arrows

A clear and precise mathematical diagram centered around a single point, from which twelve uniformly spaced blue arrows radiate outwards, representing various directions or vectors. A prominent red arc with an arrow indicates a counter-clockwise rotation, starting from a horizontal vector pointing right and concluding at a vector pointing towards the upper-left. This visual illustrates concepts fundamental to understanding angles, rotations, and vector orientation in a geometric context.
