GradoNone

GradoNone is a concept used in graph theory, a branch of mathematics, to indicate that there is no specific degree assigned to a node (or point) in a graph. In a graph, each node can have connections (edges) to other nodes, and its degree is the number of such connections. When "GradoNone" is referenced, it means that the degree information for that node is either unknown, unspecified, or intentionally ignored. This helps in scenarios where the focus is on the connections or structure of the graph without considering the exact number of links per node.
