text: Title: Feature request on native support for Dgraph database.
  Body: I see the project already supports Neo4j and Tiger graph for accessing data. I was wondering if folks would be interested in supporting [Dgraph](www.dgraph.io) ([github](https://github.com/dgraph-io/dgraph)) as well which is an open-source fast, distributed, and transactional database.
  I work with Dgraph happy to help with this addition to pygraphistry. Some of our users have showed interest in visualization capabilities that pygraphistry offers.
