title: How to prevent plotly from plotting automatically
body: <p>I just discovered plotly and like it so far. I have this code provided by the main website</p>
  
  <pre><code>import plotly.plotly as py
  from plotly.graph_objs import *
  
  trace0 = Scatter(
      x=[1,2,3,4],
      y=[10,15,13,17]
  )
  trace1 = Scatter(
      x=[1,2,3,4],
      y=[16,5,11,9]
  )
  data = Data([trace0, trace1])
  
  unique_url = py.plot(data, filename='basic-line')
  </code></pre>
  
  <p>I am curious about two things: </p>
  
  <p>1) When I run this code, my browser automatically pops up and shows me the graph. All I want is the url so that I can later embed it in an html file. Is there a way to turn off the feature that opens my browser and shows me the graph?</p>
  
  <p>2) Is there a way to get rid of the 'Play with this data' link?</p>
  
  <p>I have combed through the documentation provided, but have come up empty-handed on these two issues.</p>
