Explanation
Pharmacy orders must be displayed in four graphs as follows:
* Annual revenue over $100,000
* Annual revenues under $100,000
* Research facilities
* Hospitals
The graphs must be interactive, and users must be able to drill down on any dimension.

By using a Dynamics 365 connector, you can create flows that initiate when an event occurs in Dynamics 365, or some other service, which then performs an action in Dynamics 365, or some other service.
