set_vertex_color takes an integer vector representing membership of
some grouping (e.g., a community or connected component) and creates a
character vector of colors for each grouping. Isolated vertices will be
colored gray.
set_edge_color assigns a color to each edge (the same as the vertex
membership colors). Edges that connect vertices of two different groups are
colored gray.
