title: How to export Nvd3 charts to jpeg or png format
body: <p>Is there any better or easy way to export nvD3 chart to jpeg or png image format?
  I tried Javascript SVG parser and renderer on Canvas by using <a href="http://code.google.com/p/canvg/" rel="nofollow">http://code.google.com/p/canvg/</a>
  But in some cases (may be due to large size or greater resolution) the export option not working.</p>
