title: Getting plotly.graph_objs attribute error for FigureWidget
body: <p>I get the following error in Jupyter Notebook:</p>
  
  <pre class="lang-none prettyprint-override"><code>AttributeError: module 'plotly.graph_objs' has no attribute 'FigureWidget'
  </code></pre>
  
  <p>I have verified that Plotly package is installed as is ipywidgets, Flask and Dash.</p>
  
  <pre class="lang-py prettyprint-override"><code>from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
  import plotly.graph_objs as go
  from plotly import figure_factory as FF
  init_notebook_mode(connected=True)
  </code></pre>
  
  <p>Not sure what I need to install or update to get this to work.</p>
