# graph_from_atlas

##### Create a graph from the Graph Atlas

`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.

##### Usage

`graph_from_atlas(n)`atlas(...)

##### Arguments

- n
The id of the graph to create.

- ...
