CREATE TABLE Products (Code NUMBER, Name VARCHAR2, Price NUMBER, Manufacturer NUMBER)
CREATE TABLE Manufacturers (Code NUMBER, Name VARCHAR2, Headquarter VARCHAR2, Founder VARCHAR2, Revenue FLOAT)

Give me a bar chart to show the revenue of the company that earns the highest revenue in each headquarter city, and rank Y-axis from low to high order.
SELECT Headquarter, MAX(Revenue) FROM Manufacturers GROUP BY Headquarter ORDER BY MAX(Revenue)
SELECT "Headquarter", MAX("Revenue") FROM "Manufacturers" GROUP BY "Headquarter" ORDER BY MAX("Revenue")
