title: How to move SVG's position in D3?
body: <p>I created a svg using D3. However, it only shows up on the upper left conner of the screen, or been appended to another svg. Are there anyway I can move it using JavaScript?
  For example:</p>
  
  <pre><code>  var svg = d3.select("body").append("svg")
      .attr("width", 200)
      .attr("height", 200);
  </code></pre>
