Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Movie ( mID int, title text, year int, director text )
TABLE: CREATE TABLE Rating ( rID int, mID int, stars int, ratingDate date )
TABLE: CREATE TABLE Reviewer ( rID int, name text )

### Question ###
Return a pie chart on how many movie reviews does each director get?
