title: Unable to show chart with plotly
body: <p>I'm trying to run this example:</p>
  
  <pre><code>import plotly
  plotly.__version__
  
  import plotly.plotly as py
  import plotly.graph_objs as go
  
  from plotly.offline import download_plotlyjs, init_notebook_mode, plot,iplot
  
  
  # Create random data with numpy
  import numpy as np
  
  N = 500
  random_x = np.linspace(0, 1, N)
  random_y = np.random.randn(N)
  
  # Create a trace
  trace = go.Scatter(
      x = random_x,
      y = random_y
  )
  
  data = [trace]
  
  iplot(data, filename='basic-line')
  </code></pre>
  
  <p>But the last line iplot... is opening iPython and not showing the chart.
  How can I fix this?</p>
