instruction: A bar chart for finding the number of the names of stadiums that some Australian swimmers have been to, and could you display Y in asc order?
response: SELECT T4.Name, COUNT(T4.Name) FROM swimmer AS t1 JOIN record AS t2 ON t1.ID = t2.Swimmer_ID JOIN event AS t3 ON t2.Event_ID = t3.ID JOIN stadium AS t4 ON t4.ID = t3.Stadium_ID WHERE t1.Nationality = 'Australia' GROUP BY T4.Name ORDER BY COUNT(T4.Name)
