Flowchart.js SVG 渲染在弹出窗口中出现混乱

Question

我正在使用 flowchart.js 库来获取流程图的 SVG 渲染。我需要在带有动态 bootstrap 面板的弹出窗口中包含流程图渲染，但结果一团糟（盒子和小渲染上的标签：

我的代码是：

<div class="panel panel-default">   
  <div class="panel-body">      
    <div id="diagram"></div>    
    </div> 
</div>

<script type="text/javascript">

    $(document).ready(function () {
        var diagram = flowchart.parse('st=>start: Start:>http://www.google.com[blank]\n' +
            'e=>end:>http://www.google.com\n' +
            'op1=>operation: My Operation\n' +
            'op2=>operation: Stuff|current\n' +
            'sub1=>subroutine: My Subroutine\n' +
            'cond=>condition: Yes \n' + // use cond(align-next=no) to disable vertical align of symbols below
            'or No?\n:>http://www.google.com\n' +
            'c2=>condition: Good idea|rejected\n' +
            'io=>inputoutput: catch something...|request\n' +
            '\n' +
            'st->op1(right)->cond\n' +
            'cond(yes, right)->c2\n' + // conditions can also be redirected like cond(yes, bottom) or cond(yes, right)
            'cond(no)->sub1(left)->op1\n' + // the other symbols too...
            'c2(true)->io->e\n' +
            'c2(false)->op2->e'  //allow for true and false in conditionals
        );
        diagram.drawSVG('diagram');

    });
</script>

如何处理？

非常感谢
