CREATE TABLE actor (Actor_ID INT, Name TEXT, Musical_ID INT, Character TEXT, Duration TEXT, age INT)
CREATE TABLE musical (Musical_ID INT, Name TEXT, Year INT, Award TEXT, Category TEXT, Nominee TEXT, Result TEXT)

Calculate the number of actors in each duration of actors using a bar chart, and I want to list by the total number in ascending.
SELECT Duration, COUNT(Duration) FROM actor GROUP BY Duration ORDER BY COUNT(Duration)
SELECT "Duration", COUNT("Duration") FROM "actor" GROUP BY "Duration" ORDER BY COUNT("Duration") NULLS FIRST
