U+25D1 "◑" Circle with Right Half Black Unicode Character

U+25D1 "◑" Circle with Right Half Black is a geometric symbol that depicts a circle where the right half is filled with black, while the left half remains transparent or white, creating a visual contrast between light and dark within a single circular shape. This character belongs to the Geometric Shapes block in the Unicode standard and is often used in typography, graphical interfaces, or as a placeholder in data visualization to represent partial completeness, a binary status, or a balanced split between two states. Its design is essentially a mirror image of the related U+25D0 "◐" Circle with Left Half Black, and it can be employed in contexts where a simple, symmetrical symbolic representation of halves is required without relying on more complex imagery.
