无法在引导程序 div 上插入 d3 图表



我需要把一个d3图表在HTMLdiv使用bootstrap，但我不能。我设法把它附在身体上，但我不知道为什么我不能在一个div。我在脚本中使用如下代码:

 var chart1 = d3.select("#chart1")
.append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
.append("g")

和html:

的简单方式
  <div id="chartline1"></div>

下面是所有的代码:

必须在调用脚本之前声明div。把脚本放在它后面或封装在一个函数中，并在加载时调用它。
