SELECT Class, COUNT(Class) FROM race GROUP BY Class ORDER BY Class DESC
Show me how many in each class of all races using a bar chart, and I want to order in descending by the Class.
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 real,
    Year_Opened real
)
