\title{Create a graph from the Graph Atlas}
\usage{
graph_from_atlas(n)
atlas(...)

}
\value{
An igraph graph.
}
\description{
\code{graph_from_atlas} creates graphs from the book
\sQuote{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:
\enumerate{
\item in increasing order of number of nodes;
\item for a fixed number of nodes, in increasing order of the number
of edges;
\item for fixed numbers of nodes and edges, in increasing order of
the degree sequence, for example 111223 < 112222;
\item for fixed degree sequence, in increasing number of
automorphisms.
}
}
\examples{
## Some randomly picked graphs from the atlas
graph_from_atlas(sample(0:1252, 1))
graph_from_atlas(sample(0:1252, 1))
