text: Title: Interactive Visualizer demos with Binder
  Body: Using Ipywidgets, we can create interactive Yellowbrick visualizations.  I would like to allow other users to see these interactive demos using Binder.   Currently our README has a Binder button that launches a Docker with our examples.ipynb notebook viewable.  This allows users can interact with it without having to clone YB and run the notebooks locally.  Additional research is needed to determine how Binder can show the demos.
