D3 Charts

Drag on canvas is not working.

To fix need to Add .subject(dragsubject) to d3.drag()
return d3.drag()
      .subject(dragsubject)
      .on("start", dragstarted)
      .on("drag", dragged)
      .on("end", dragended);

And add this function

  function dragsubject(event) {
    return simulation.find(event.sourceEvent.offsetX, event.sourceEvent.offsetY);
  }
