Sample code for calling admin/virtual_graphs/import

Not exactly .. which is why I published an example.

The way that I figured out how to use the endpoint was:

In the end it was simple, but it took a few guesses and false starts to stumble my way to success.

Since this seems like a particularly handy ETL method, I figured it was worth publishing a simple example to save fellow travelers some time.

Our use case involves ingesting event records from Veeva Vault QMS, so this method seems almost perfect for building a "Quality Event KG" on an event driven basis .. i.e. our agent subscribes to the event system, and stuffs mapped records into the KG upon receipt .. basically a "one-hop" ingestion pipeline with declarative transformation of content (via SMS) .. pretty much as elegant as it gets.
