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 Reviewer ( rID int, name text )
TABLE: CREATE TABLE Rating ( rID int, mID int, stars int, ratingDate date )

### Question ###
Return a histogram on what is the average number of stars that each reviewer awards for a movie?, and I want to display x-axis in desc order please.

### Accurate SQL ###

SELECT name, AVG(T1.stars) FROM Rating AS T1 JOIN Reviewer AS T2 ON T1.rID = T2.rID GROUP BY T2.name ORDER BY name DESC
