Getting an error message when navigating away from a screen using this component.  I noticed that the same error appears when using the sample application and clicking on the home link in the top left of the screen.  

Looking at the console we get the following message when attempting to navigate away from the page with the Sankey Diagram.     

ErrorScreen.js:54 Mismatched anonymous define() module: function(exports, d3Array, d3Collection, d3Shape) {

'use strict';

function targetDepth(d) {

  return d.target.depth;

}

function left(node) {

  return node.depth;

}

function right(node, n) {

  return n - 1 - node.height;

}

function justify(node, n) {

  return node.sourceLinks.length ? node.depth : n - 1;

}

function customColumn(node) {

  return node.column;

}

function center(node) {

  return node.targetLinks.length ? node.depth

      : node.sourceLinks.length ? d3Array.min(node.sourceLinks, targetDepth) - 1

      : 0;

}
