CREATE TABLE Reviewer (rID INT, name TEXT)
CREATE TABLE Rating (rID INT, mID INT, stars INT, ratingDate DATE)
CREATE TABLE Movie (mID INT, title TEXT, year INT, director TEXT)

Please give me a bar chart to compare the stars by directors, and list by the X-axis from high to low.
SELECT director, stars FROM Rating AS T1 JOIN Movie AS T2 ON T1.mID = T2.mID ORDER BY director DESC
SELECT "director", "stars" FROM "Rating" AS "T1" JOIN "Movie" AS "T2" ON "T1"."mID" = "T2"."mID" ORDER BY "director" DESC NULLS LAST
