Graph Annotations

Graph annotations, also known as attributes, are used to set and store values associated with vertices, edges and the graph itself. Standard annotations typically related to styles, labels and weights extended the graph-modeling capabilities and are handled automatically by all graph-related functions. User-defined annotations allow for many further extensions of graph modeling.
