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

Show me a bar chart for what are the nationalities and total ages of journalists?, I want to sort by the x-axis in asc.
SELECT Nationality, SUM(Age) FROM journalist GROUP BY Nationality ORDER BY Nationality
SELECT "Nationality", SUM("Age") FROM "journalist" GROUP BY "Nationality" ORDER BY "Nationality" NULLS FIRST
