CREATE TABLE PersonFriend (name VARCHAR, friend VARCHAR, year INT)
CREATE TABLE Person (name VARCHAR, age INT, city TEXT, gender TEXT, job TEXT)

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") NULLS FIRST
