CREATE TABLE ship (Ship_ID INT, Name TEXT, Type TEXT, Nationality TEXT, Tonnage INT)
CREATE TABLE mission (Mission_ID INT, Ship_ID INT, Code TEXT, Launched_Year INT, Location TEXT, Speed_knots INT, Fate TEXT)

What is the total number of each ship type? Give me a bar chart, and list Type in desc order.
SELECT Type, COUNT(Type) FROM ship GROUP BY Type ORDER BY Type DESC
SELECT "Type", COUNT("Type") FROM "ship" GROUP BY "Type" ORDER BY "Type" DESC NULLS LAST
