    Make a Pandana network from a bounding lat/lon box
    request to the Overpass API. Distance will be in the default units meters.

    Parameters
    ----------
    lat_min, lng_min, lat_max, lng_max : float
    bbox : tuple
        Bounding box formatted as a 4 element tuple:
        (lng_max, lat_min, lng_min, lat_max)
    network_type : {'walk', 'drive'}, optional
        Specify whether the network will be used for walking or driving.
        A value of 'walk' attempts to exclude things like freeways,
        while a value of 'drive' attempts to exclude things like
        bike and walking paths.
    two_way : bool, optional
        Whether the routes are two-way. If True, node pairs will only
        occur once.
    timeout : int, optional
        the timeout interval for requests and to pass to Overpass API
    memory : int, optional
        server memory allocation size for the query, in bytes.
        If none, server will use its default allocation size
    max_query_area_size : float, optional
        max area for any part of the geometry, in the units the geometry is in
