在D3中将堆叠条形图的方向从垂直改为水平

我正在将响应式堆叠条形图的方向从垂直更改为水平，但在更改内容后没有显示任何内容，下面是一些来自堆栈流的其他示例，如这里和这里。这涉及到堆叠条形图下面是我在fiddle

但是当前的工作代码在这里

  var margin = {
        top: 20,
        right: 160,
        bottom: 35,
        left: 30
      };
      var width = 600 - margin.left - margin.right,
        height = 600 - margin.top - margin.bottom;
      var svg = d3.select("body")
        .append("svg")
        .attr("width", width + margin.left + margin.right)
        .attr("height", height + margin.top + margin.bottom)
        .append("g")
        .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
