instead of using size[0], width variable will trigger wrong size of the sankey diagram

[Yanz2015]

function computeNodeBreadths() {
var remainingNodes = nodes,
nextNodes,
x = 0;

while (remainingNodes.length) {
  nextNodes = [];
  remainingNodes.forEach(function(node) {
    node.x = x;
    node.dx = nodeWidth;
    node.sourceLinks.forEach(function(link) {
      nextNodes.push(link.target);
    });
  });
  remainingNodes = nextNodes;
  ++x;
}

//
moveSinksRight(x);
scaleNodeBreadths((width - nodeWidth) / (x - 1));

}

in this function the last line scaleNodeBreadthes, the variable width is using a context variable, but not the size[0], which is given to initialize the sankey diagram. so it will trigger wrong layout when the width variable is wrong evaluated.
