title: Why don't the circles show up?
body: <p>I built some SVG with d3.js but nothing is displayed. Why? Here is part of code:</p>
  
  <pre><code>&lt;svg width="863" height="863" id="svgId"&gt;
  &lt;g transform="translate(431.5,431.5)"&gt;
      &lt;g class="asdf" r="421.5"&gt;
          &lt;circle transform="translate(0,0)" style="fill: rgb(255, 0, 0);"&gt;&lt;/circle&gt;
      &lt;/g&gt;
      &lt;g class="asdf" r="127.6354829132969"&gt;
          &lt;circle transform="translate(-118.50486492278469,167.13470131539657)" style="fill: rgb(255, 0, 0);"&gt;&lt;/circle&gt;
      &lt;/g&gt;
  &lt;/g&gt;
  </code></pre>
