title: d3 v4 function gives TypeError: d3.timeParse is not a function
body: <p>I loaded d3 v4 but it gives error at line below:
  var parseTime = d3.timeParse("%Y");
  TypeError: d3.timeParse is not a function </p>
  
  <p>Not sure if this happens because I loaded also v3  which is used for another component. But it shouldn't since the message is about not finding the function.</p>
