CREATE TABLE Products (Code INT, Name VARCHAR, Price DECIMAL, Manufacturer INT)
CREATE TABLE Manufacturers (Code INT, Name VARCHAR, Headquarter VARCHAR, Founder VARCHAR, Revenue FLOAT)

Give me a bar chart with the headquarters and revenues for manufacturers, sorted by revenue descending.
SELECT Headquarter, Revenue FROM Manufacturers ORDER BY Revenue DESC
SELECT "Headquarter", "Revenue" FROM "Manufacturers" ORDER BY "Revenue" DESC NULLS LAST
