I'm building a course related to sales and need to define an important term: account. The requestor would like to use the concept of an umbrella that is overarching the various other terms that are types of accounts, ie) customers, competitors, prospects, and customer/competitor combo. While the umbrella graphic might show the proper relationship, it is out of context for the rest of the course. Any ideas of how to graphically represent this relationship? Thanks for your help!
