title: render dc.js charts on brushmove instead of brushend
body: <p>I'm trying to render a visualization with dc.js that responds immediately to brushmove events.</p>
  <p>It seems that dc.js charts will only re-render when the brush stops moving (<a href="https://dc-js.github.io/dc.js/crime/index.html" rel="nofollow noreferrer">example with dc brushend rendering</a>), instead of simultaneous with the brush movement (<a href="https://bl.ocks.org/alexmacy/ebe599703421757852d36bcf71174dfc" rel="nofollow noreferrer">example with brushmove rendering</a>).</p>
  <p>Is there any way to modify this behavior so that all dc charts will re-render simultaneously with the brush movement?</p>
