User-configurable BI dashboards for document data stores?

It seems that most common BI tools (PowerBI, Tableau, Looker) require data to be in a relational model in order to have a good experience with the tool.

When Mongo is listed as a supported data store it appears to be via a relational wrapper service (https://docs.mongodb.com/bi-connector/current/).

Are there any dashboarding tools that offer good native support for data in a document store?
