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

What is the total number of different nationalities of all ships? Give me a bar graph, and list in asc by the X please.
SELECT Nationality, COUNT(Nationality) FROM ship GROUP BY Nationality ORDER BY Nationality
SELECT "Nationality", COUNT("Nationality") FROM "ship" GROUP BY "Nationality" ORDER BY "Nationality" NULLS FIRST
