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

Show me how many in each class of all races using a bar chart, show in descending by the Y-axis.
SELECT Class, COUNT(Class) FROM race GROUP BY Class ORDER BY COUNT(Class) DESC
SELECT "Class", COUNT("Class") FROM "race" GROUP BY "Class" ORDER BY COUNT("Class") DESC NULLS LAST
