Draw an ERD for the following description:

We store each employee$$s name $($first$,$ last, MI$),$ Social Security number $($SSN$),$ street address, salary, sex $($gender$),$ and birth date. An employee is assigned to one department, but may work on several projects, which are not necessarily controlled by the same department. We keep track of the current number of hours per week that an employee works on each project. We also keep track of the direct supervisor of each employee $($who is another employee$).$

Assignment Expectations:

$(1)$ A drawn ERD. You may use a free online tool $($CanvaLinks to an external site., LucidChartLinks to an external site., or otherwise$)$ or you may hand$-$draw but it MUST be legible. This must be done in a way that clearly shows entities, attributes, relationships, etc.

$(2)$ A brief explanation of why you choose relationship types between entities. For example, if you said a relationship from Entity A is one$-$to$-$many with Entity B$,$ why?
