CREATE TABLE PersonFriend (name VARCHAR2, friend VARCHAR2, year NUMBER)
CREATE TABLE Person (name VARCHAR2, age NUMBER, city CLOB, gender CLOB, job CLOB)

Visualize a bar chart for what is average age for different job title?, I want to show from low to high by the the average of age.
SELECT job, AVG(age) FROM Person GROUP BY job ORDER BY AVG(age)
SELECT "job", AVG("age") FROM "Person" GROUP BY "job" ORDER BY AVG("age")
