title: how to add a noflo chart/plot component
body: <p>I have a time-series-style array of data I would like to pass into a noflo component which displays the data in a cart/graph/plot using the browser runtime and the flowhub ui.</p>
  
  <p>I've browsed through the <a href="http://noflojs.org/library/" rel="nofollow">component library</a> and not found a relevant component. I'm familiar with several charting libraries and am willing to write it myself, but am unsure how to fit this into a component. </p>
  
  <ol>
  <li>is there a charting/plotting component that I missed?
  I've seen <a href="http://noflojs.org/library/noflo-ducksboard/" rel="nofollow">noflo-ducksboard</a>, but I really want to be able to view the plot from within the noflo-ui.</li>
  <li>how might I load a charting library into a component?</li>
  <li>is there a particular charting library you suggest I use?</li>
  </ol>
