title: Adding hyperlinks to Shiny plots
body: <p>I have made a Shiny app using different plotting solutions to render graphs from <code>ggplot2</code> on Shiny (my favorite being <code>plotly</code>).<br>
   I like the fact that the user can interact with the graph: with <code>plotly</code> the user can zoom on the graph or click on points (on a scatterplot for exemple) and access their values.  </p>
  
  <p>I would like to link each point on my scatterplot to a URL (without displaying it) and to allow the user to click on a dot, which would trigger the activation of the hyperlink opening a new webpage.    </p>
  
  <p>If I could use plotly to do that that would be amazing but I am open to any other kind of technologies (<code>ggvis</code>,<code>dygraph</code>, etc.).</p>
