CREATE TABLE train (Train_ID NUMBER, Name CLOB, Time CLOB, Service CLOB)
CREATE TABLE station (Station_ID NUMBER, Name CLOB, Annual_entry_exit FLOAT, Annual_interchanges FLOAT, Total_Passengers FLOAT, Location CLOB, Main_Services CLOB, Number_of_Platforms NUMBER)
CREATE TABLE train_station (Train_ID NUMBER, Station_ID NUMBER)

Give me a bar chart about the number of platforms in different locations, show total number in asc order.
SELECT Location, SUM(Number_of_Platforms) FROM station GROUP BY Location ORDER BY SUM(Number_of_Platforms)
SELECT "Location", SUM("Number_of_Platforms") FROM "station" GROUP BY "Location" ORDER BY SUM("Number_of_Platforms")
