CREATE TABLE journalist (journalist_ID NUMBER, Name CLOB, Nationality CLOB, Age CLOB, Years_working NUMBER)
CREATE TABLE news_report (journalist_ID NUMBER, Event_ID NUMBER, Work_Type CLOB)
CREATE TABLE event (Event_ID NUMBER, Date CLOB, Venue CLOB, Name CLOB, Event_Attendance NUMBER)

A bar chart about what are the nationalities and their average ages of journalists?, I want to rank by the x axis from low to high.
SELECT Nationality, AVG(Age) FROM journalist GROUP BY Nationality ORDER BY Nationality
SELECT "Nationality", AVG("Age") FROM "journalist" GROUP BY "Nationality" ORDER BY "Nationality"
