Review comment:
Rephrasing to
```
"""Record references to all user-defined pipeline instances watched in
current environment.
Current static global singleton interactive environment holds references
to
a set of pipeline instances defined by the user in the watched scope.
Interactive Beam features could use the references to determine if a
given
pipeline is defined by user or implicitly created by Beam SDK or runners,
then handle them differently.
This is invoked every time a PTransform is to be applied if the current
code execution is under ipython due to the possibility that any
user-defined
pipeline can be re-evaluated through notebook cell re-execution at any
time.
Each time this is invoked, the tracked user pipelines are refreshed to
remove any pipeline instances that are no longer in watched scope. For
example, after a notebook cell re-execution re-evaluating a pipeline
creation, the last pipeline reference created by last evaluation will
not be
in watched scope anymore.

> Key: BEAM-7926
> URL: https://issues.apache.org/jira/browse/BEAM-7926
> Project: Beam
> Issue Type: New Feature
> Components: runner-py-interactive
> Reporter: Ning Kang
> Assignee: Ning Kang
> Priority: Major
> Time Spent: 22h 40m
> Remaining Estimate: 0h
>
> Support auto plotting / charting of materialized data of a given PCollection
> with Interactive Beam.
> Say an Interactive Beam pipeline defined as
>
> {code:java}
> p = beam.Pipeline(InteractiveRunner())
> pcoll = p | 'Transform' >> transform()
> pcoll2 = ...
> pcoll3 = ...{code}
> The use can call a single function and get auto-magical charting of the data.
> e.g.,
> {code:java}
> show(pcoll, pcoll2)
> {code}
> Throughout the process, a pipeline fragment is built to include only
> transforms necessary to produce the desired pcolls (pcoll and pcoll2) and
> execute that fragment.
> This makes the Interactive Beam user flow data-centric.
