Interactively visualize a billion points with Dask and Datashader.

This takes an example from Anaconda (thanks @Peter Wang!) visualizing the NYC Taxi data with Dask. When we start it takes a minute to render the dataset. Then, after doing a bit of performance tuning we make this fast enough to render interactively (about a second per update). This enables us to interact live with a large dataset.
