title: Time-series histogram
body: <p>Is it possible to create a time-series histogram like the one described in <a href="http://www.slideshare.net/postwait/its-all-about-telemetry" rel="nofollow">this</a> presentation (slides 36-39) using either R or D3.js?  Or is there a better way to show bucketed data as a time series?</p>
  
  <p>Edit: Here is some pre-bucketed <a href="https://gist.github.com/3188612" rel="nofollow">sample data</a>. Ideally, D3 or R would do the bucketing by itself.  And yes, if it wasn't clear, I understand that I could write this myself.  I'm just wondering if there's already a package that does this and I just haven't come across it yet.  Thanks!</p>
