How to select DOM elements with number value id using D3
<p>All:</p>

<p>I wonder how do I select a DIV element with id="1" in D3, I can do it in jQuery, but when I turn to D3, it gives error like:</p>

<blockquote>
  <p>Uncaught DOMException: Failed to execute 'querySelector' on
  'Document': 'div.chart#1' is not a valid selector</p>
</blockquote>

<pre><code>&lt;div id="1"&gt;&lt;/div&gt;
</code></pre>

<p>Thanks</p>
