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 all ships' nationalities with a bar graph, and order Nationality in asc order.
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
