text: Title: [DOCS] Gremlin Part II demo notebook
  Body: **Is your feature request related to a problem? Please describe.**
  
  More examples (and support)
  
  **Describe the solution you'd like**
  
  - [ ] Neptune Sagemaker instance <> graphistry server
  - [ ] Passing gremlinpython objects to pygraphistry, including via magics
  - [ ] Top queries: sampling, search & expand, connect-the-dots, ...
  - [ ] Add transforms & enrichments
  - [ ] Writebacks
  
  **Describe alternatives you've considered**
  
  - APIs should support, but a notebook should make top cases clear
  - Do as a Part II to current, vs making current overwhelming
  
  **Additional context**
  Similar use cases in graph-app-kit
