CREATE TABLE school_bus (School_ID INT, Driver_ID INT, Years_Working INT, If_full_time BOOLEAN)
CREATE TABLE school (School_ID INT, Grade TEXT, School TEXT, Location TEXT, Type TEXT)
CREATE TABLE driver (Driver_ID INT, Name TEXT, Party TEXT, Home_city TEXT, Age INT)

Please give me a pie chart to show the number of home cities of all drivers
SELECT Home_city, COUNT(Home_city) FROM driver GROUP BY Home_city
SELECT "Home_city", COUNT("Home_city") FROM "driver" GROUP BY "Home_city"
