title: AttributeError: module 'chart_studio.plotly' has no attribute 'offline'
body: <p>I am quite struggling with plotly offline mode in jupyter notebook.  I used to use import plotly.plotly as py and then use py.offline.plot().  Now it tells me plotly.plotly is depreciated and want me to use chart_studio.plotly. Now I don't know how to use offline mode for chart_studio.plot.  I either got an error of Authentication is required or chart_studio doesn't have offline mode. I just want to plot some figures in jupyter notebook using plotly. How can I fix the issue? Thanks</p>
  <pre><code>
  import chart_studio.plotly as py
  from chart_studio.grid_objs import Grid, Column
  import plotly.figure_factory as FF
  import pandas as pd
  import time
  import pickle
  
  filename_pickle='dataset.pkl'
  try:
      dataset=pd.read_pickle(filename_pickle)
  except FileNotFoundError: 
      url = 'https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv'
      dataset = pd.read_csv(url)
      dataset.to_pickle(filename_pickle)
  
  table = FF.create_table(dataset.head(10))
  #py.iplot(table, filename='animations-gapminder-data-preview')
  py.offline.iplot(table)
  
  Previously: I use plotly.plotly 
  
  import plotly.plotly as py
  from plotly.grid_objs import Grid, Column
  from plotly.tools import FigureFactory as FF
  
  # chart_studio is for online mode only
  # import chart_studio.plotly as py
  # from chart_studio.grid_objs import Grid, Column
  # import plotly.figure_factory as FF
  
  import pandas as pd
  import time
  import pickle
  
  filename_pickle='dataset.pkl'
  try:
      dataset=pd.read_pickle(filename_pickle)
  except FileNotFoundError: 
      url = 'https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv'
      dataset = pd.read_csv(url)
      dataset.to_pickle(filename_pickle)
  
  table = FF.create_table(dataset.head(10))
  #py.iplot(table, filename='animations-gapminder-data-preview')
  py.offline.iplot(table)
  
  then I got an error of 
  ImportError: 
  The plotly.plotly module is deprecated,
  please install the chart-studio package and use the
  chart_studio.plotly module instead.
