Solve the following python programming problem given the following code:
@nx.utils.open_file(5, 'w')
def view_pygraphviz(G, edgelabel=None, prog='dot', args='', suffix='', path=None):
assistant
#Here is the Python code you requested.

    """Views the graph G using the specified layout algorithm.
    Parameters
    G : NetworkX graph
    The machine to draw.
    edgelabel : str, callable, None
    If a string, then it specifes the edge attribute to be displayed
    on the edge labels. If a callable, then it is called for each
    edge and it should return the string to be displayed on the edges.
    The function signature of `edgelabel` should be edgelabel(data),
    where `data` is the edge attribute dictionary.
    prog : string
    Name of Graphviz layout program.
    args : str
    Additional arguments to pass to the Graphviz layout program.
    suffix : str
    If `filename` is None, we save to a temporary file.  The value of
    `suffix` will appear at the tail end of the temporary filename.
    path : str, None
    The filename used to save the image.  If None, save to a temporary
    file.  File formats are the same as those from pygraphviz.agraph.draw.
    Returns
    path : str
    The filename of the generated image.
    A : PyGraphviz graph
    The PyGraphviz graph instance used to generate the image.
    Notes
    If this function is called in succession too quickly, sometimes the
    image is not displayed. So you might consider time.sleep(.5) between
    calls if you experience problems.
