title: How do I view a live execution of a dask graph?
body: <p>In several talks about Dask, an animated task graph is shown with nodes coloured red as they are run and blue as they are completed (example: <a href="https://youtu.be/RA_2qdipVng?t=23m57s" rel="nofollow noreferrer">https://youtu.be/RA_2qdipVng?t=23m57s</a>). I couldn't find this functionality in the documentation. Is it easy/possible for a user to produce this visualisation for their tasks?</p>
