The reporting DB in my case is Redshift. The business use case isn't exactly charting. My goal is to enable a business user to reference certain types of important aggregates in Google Sheets. By enabling this, business users can then compose tabular views of data that are rich, dense, and always correct and up to date. It also allows business users to very quickly prototype dashboards and make detailed specs for reports before an analyst or engineer has to get involved.

This is one tool in our tool belt for communicating with data. We also have an in house SQL-in-chart-out platform that everyone has access to and we have Looker for deeper exploratory work.
