Incorrect us of donut graphics for message delivery reporting

Hi MH devs.

Just some feedback. In the Journey Reports - > Message-Based reporting there is a donut graph that shows all of the following:

Sent, Delivered, Bounced, Opened, Clicked and Unsubscribed.

These numbers should NOT be combined as a donut graphic, as the pictorial representation is incorrect.  For example, Sent is made up of Delivered, Bounced, but NOT Opened (which is a subset of delivered).  Likewise clicked and unsubscribed is a sub-set of opened. 

This is a not a major deal breaker, but is does lead to an  incorrect visual of what is happening with messaging in journeys.
