Query vertex attributes of a graph
vertex_attr(graph, name, index = V(graph))The graph.
Name of the attribute to query. If missing, then all vertex attributes are returned in a list.
A vertex sequence, to query the attribute only for these vertices.
The value of the vertex attribute, or the list of
all vertex attributes, if name is missing.
