我想了解一下D3，我需要将有些混乱和复杂的SVG路径数据转换为D3可以理解的简单数字，以便复制路径。我已经在Illustrator中手动创建了一个SVG：

<svg xmlns="http://www.w3.org/2000/svg" width="558.79" height="291.94" viewBox="0 0 558.79 291.94">

对于那些好奇的人来说，它看起来是这样的：

我想用D3来绘制同样的路径。所以我需要一些方法来将路径数据（d）转换成D3可以理解的值，去掉所有的M、C、L等。下面是D3的代码：

var path = svg.append("path")
      .attr("d", line(data))
      .attr("id","myPath")
      .attr("stroke", "red")
      .attr("stroke-width", "2")
      .attr("fill", "none");

数据变量需要类似于：

var data = [1.48, 291.72, 3.83, 26.14, 1.05, 7.21...etc];

在数据数组中的一组随机数中，路径可以很好地工作。我已经花了好几个小时在这里尝试各种方法，但最终，到目前为止提出的许多问题似乎要做比我需要执行的（看似）简单的提取/转换更复杂的事情。
感谢您的帮助！：）
