title: 3D vector field in matplotlib
body: <p>Is there a way to plot a 3D vector field in matplotlib? I have seen <a href="http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.quiver" rel="noreferrer">quiver</a>, but it only talks about a "2-D vector field of arrows". Is there a 3D counterpart somewhere?</p>
  
  <p>LMGTFY:<br>
  I figured a documentation for the 3D counterpart would be returned by this search term:</p>
  
  <pre><code>"3-D vector field of arrows" matplotlib
  </code></pre>
  
  <p>But it returns zero results</p>
