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)

Show me the comparison of the total number of every ship type with a bar graph, 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
