# 2D Grid

Illustrate `write_dot` in conjunction with the Graphviz command line interface to create visualizations.

    import matplotlib.pyplot as plt
    import networkx as nx

Write a dot file from a networkx graph for further processing with graphviz.

    G = nx.grid_2d_graph(5, 5)  # 5x5 grid
    # This example needs Graphviz and PyGraphviz
    nx.nx_agraph.write_dot(G, "grid.dot")
    # Having created the dot file, graphviz can be invoked via the command line
    # to generate an image on disk, e.g.
    print("Now run: neato -Tps grid.dot >grid.ps")

    # Alternatively, the and image can be created directly via AGraph.draw
    A = nx.nx_agraph.to_agraph(G)
    A.draw("5x5.png", prog="neato")

    Now run: neato -Tps grid.dot >grid.ps
