CREATE TABLE train (id INT, train_number INT, name TEXT, origin TEXT, destination TEXT, time TEXT, interval TEXT)
CREATE TABLE station (id INT, network_name TEXT, services TEXT, local_authority TEXT)
CREATE TABLE route (train_id INT, station_id INT)
CREATE TABLE weekly_weather (station_id INT, day_of_week TEXT, high_temperature INT, low_temperature INT, precipitation FLOAT, wind_speed_mph INT)

Give me a bar chart for the number of services of each services, sort in ascending by the services.
SELECT services, COUNT(services) FROM station GROUP BY services ORDER BY services
SELECT "services", COUNT("services") FROM "station" GROUP BY "services" ORDER BY "services" NULLS FIRST
