CREATE TABLE aircraft (aid NUMBER, name VARCHAR2, distance NUMBER)
CREATE TABLE certificate (eid NUMBER, aid NUMBER)
CREATE TABLE flight (flno NUMBER, origin VARCHAR2, destination VARCHAR2, distance NUMBER, departure_date DATE, arrival_date DATE, price NUMBER, aid NUMBER)
CREATE TABLE employee (eid NUMBER, name VARCHAR2, salary NUMBER)

Bar chart of the total number from each origin, I want to sort from low to high by the y axis.
SELECT origin, COUNT(*) FROM flight GROUP BY origin ORDER BY COUNT(*)
SELECT "origin", COUNT(*) FROM "flight" GROUP BY "origin" ORDER BY COUNT(*)
