CircleNone

CircleNone is a term often used in programming to represent the absence of a specific circle object or value. Essentially, it indicates that there is no circle currently defined or available in a given context. Think of it as a placeholder or null value for a circle, used to handle situations where a circle might be expected but isn’t provided. This helps prevent errors in the code by clearly signaling that no circle exists, allowing developers to manage such cases gracefully.
