Bar chart of how many local authority from each local authority, and could you order names in descending order?
SELECT local_authority, COUNT(local_authority) FROM station GROUP BY local_authority ORDER BY local_authority DESC
SELECT "local_authority", COUNT("local_authority") FROM "station" GROUP BY "local_authority" ORDER BY "local_authority" DESC
