The circled dot operator (⊙) is a mathematical symbol primarily used to represent specialized operations like the Hadamard product (element-wise multiplication) for matrices. In physics, it often illustrates a vector pointing directly out of the page toward the viewer. Beyond technical fields, it occasionally appears in digital art and typography as a stylized target, an eye, or a representation of the sun.
