title: Attempted import error: 'behavior' is not exported from 'd3'
body: <p>I am trying to make a sankey diagram using d3 and react.js and I am using this example as a reference <a href="https://bl.ocks.org/emeeks/9673c96a682fe3948379" rel="noreferrer">https://bl.ocks.org/emeeks/9673c96a682fe3948379</a>. I am fairly new to react(2 days) and I am getting this error-- </p>
  
  <pre><code>./src/components/SankeyComponent.js
  </code></pre>
  
  <p>Attempted import error: 'behavior' is not exported from 'd3' (imported as 'd3').</p>
  
  <p>SankeyComponent.js
  This is my code for creating SankeyComponent. As soon as I clear one error other import and export erros are coming up.</p>
