Consider adding show and/or draw method to SuperComponent to easily plot the underlying pipeline

[sjrl]

It was brought up here that it isn't immediately intuitive to figure out how to display the mermaid graph of the underlying pipeline in a SuperComponent.

It could be nice to add show and draw methods to the BaseSuperComponent class to better expose these options.

In the meantime users should be able to do MySuperComponent().pipeline.show() to visualize the pipeline graph.
