👉 A dagger is a symbol or device used to denote a specific part of an object. It can be used in various contexts, such as in mathematics or physics, and can have different meanings depending on its usage.
In mathematics, a dagger is often used to denote a set of points that are not connected by any line segments (edges) but are connected by some other type of shape or structure (like circles, lines, etc.). This notation helps in distinguishing these sets from the rest of the graph
