CREATE TABLE race (Race_ID NUMBER, Name CLOB, Class CLOB, Date CLOB, Track_ID CLOB)
CREATE TABLE track (Track_ID NUMBER, Name CLOB, Location CLOB, Seating FLOAT, Year_Opened FLOAT)

Give me a bar chart for the total number of each class, sort in desc by the bars.
SELECT Class, COUNT(*) FROM race GROUP BY Class ORDER BY Class DESC
SELECT "Class", COUNT(*) FROM "race" GROUP BY "Class" ORDER BY "Class" DESC
