grid_2d_graph(m, n, periodic=False, create_using=None)[source]#

Returns the two-dimensional grid graph.

The grid graph has each node connected to its four nearest neighbors.

m, nint or iterable container of nodes

If an integer, nodes are from range(n). If a container, elements become the coordinate of the nodes.

periodicbool or iterable

If periodic is True, both dimensions are periodic. If False, none are periodic. If periodic is iterable, it should yield 2 bool values indicating whether the 1st and 2nd axes, respectively, are periodic.

create_usingNetworkX graph constructor, optional (default=nx.Graph)

Graph type to create. If graph instance, then cleared before populated.

NetworkX graph

The (possibly periodic) grid graph of the specified dimensions.
