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

Show me how many in each class of all races using a bar chart, and sort by the the number of class in ascending.
SELECT Class, COUNT(Class) FROM race GROUP BY Class ORDER BY COUNT(Class)
SELECT "Class", COUNT("Class") FROM "race" GROUP BY "Class" ORDER BY COUNT("Class") NULLS FIRST
