Use this if you are using igraph from R

`graph_from_atlas`

creates graphs from the book
‘An Atlas of Graphs’ by
Roland C. Read and Robin J. Wilson. The atlas contains all undirected
graphs with up to seven vertices, numbered from 0 up to 1252. The
graphs are listed:

in increasing order of number of nodes;

for a fixed number of nodes, in increasing order of the number of edges;

for fixed numbers of nodes and edges, in increasing order of the degree sequence, for example 111223 < 112222;

for fixed degree sequence, in increasing number of automorphisms.
