title: Open a url by clicking a data point in plotly?
body: <p>I have successfully created plotly graphs from python, and gone as far as creating custom html tooltips for the datapoints. But I haven't succeeded in adding functionality to open a link if someone clicks on a datapoint. What I would like is a separate tab to pop up showing more information linked to that particular data point.</p>
  
  <p>Can anyone think of a way to achieve this with plotly?</p>
