为什么在这个很小的示例中未调用.await函数？

http://jsfiddle.net/x2fkvsco/

的HTML

<h1>test</h1>
<div id="a"></div>
<div id="b"></div>

JS

d3.queue()
   .defer(a,1)
   .await(b,2);

function a(x){
    d3.select('#a').text("a is executing with x="+x);
}

function b(err,x){
   d3.select('#b').text("b is executing with x="+x);
}

输出量

test
a is executing with x=1
