title: Getting started with d3.js, what files are needed?
body: <p>I am trying to get start with <em>d3.js</em> and have downloaded the latest release from <a href="https://github.com/dc-js/dc.js/releases" rel="nofollow noreferrer">https://github.com/dc-js/dc.js/releases</a>. Other than the <em>d3.js</em> file, there are a lot of other scripts in the <strong>src</strong> and <strong>spec</strong> folders.</p>
  
  <p>Do we need to put all these into our own project directory? Or it is enough to copy the <em>d3.js</em> file?</p>
