title: SVG chart generation in JavaScript
body: <p>I'm looking for a way to generate pie charts using SVG.</p>
  
  <p>The numbers I have are simple enough - just percentages, an array of numbers that obviously add up to 100.</p>
  
  <p>I have a basic understanding of SVG, but I can't think how to translate these numbers into meaningful coordinates to use in the path tag</p>
  
  <p>Can anyone point me to a useful utility or library, or give any hints as to how I could use percentages to draw a pie chart - in JavaScript?</p>
