text: Title: [DOCS] CosmosDB notebook
  Body: We should have an explicit cosmosdb tutorial notebook series:
  
  - [ ] connection info, incl pk usage
  - [ ] df -> cosmos
  - [ ] query -> cosmos -> graph
  - [ ] node/edge enriching
  - [ ] and viz, of course :)
  
  An internal hub notebook sketches a bunch of these from before we had the integration, which may be a good start
