 Review comment:
   I would suggest first option. Require installation of full [interactive] 
extra package.

> Support auto plotting / charting of materialized data of a given PCollection 
> with Interactive Beam.
> Say an Interactive Beam pipeline defined as
> p = create_pipeline()
> pcoll = p | 'Transform' >> transform()
> The use can call a single function and get auto-magical charting of the data 
> as materialized pcoll.
> e.g., visualize(pcoll)
