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)

Show me a stacked bar graph, the x-axis is the nationality of ship, and the y-axis is their total number of different nationality and split by ship type, sort x-axis in ascending order.
SELECT Nationality, COUNT(Nationality) FROM ship GROUP BY Type, Nationality ORDER BY Nationality
SELECT "Nationality", COUNT("Nationality") FROM "ship" GROUP BY "Type", "Nationality" ORDER BY "Nationality" NULLS FIRST
